Gary's experience actually shows the real reason there's so much variation on Slant parts, compared to modern engines. Slants were pumped out as fast as possible, in an era before CNC and assembly robots, the pressure to push them out to meet demand is what led to lower quality control, and that is true of all high volume production of the 60's and 70's.

Having worked in the Tool Room of an engine plant I can absolutely confirm that their were foremen that were completely concerned about their numbers. I remember one time I got sent out because they were having a problem with actually pushing the blocks off of the fixture clamping pads. The production foreman wanted the hydraulic pressure turned up. Putting a gage on the pump I found it was already at the specified pressure. I then asked the set-up man to pull one of the drills out. The drills were completely shot in terms of cutting ability. This was on main bearing cap tapped holes. Turned out the drills were a week past their scheduled change point. Something on the order of 4000 machine cycles. Sharp drills, every thing worked fine. Another time we spent a weekend rebuilding a milling head that cut the top of the head on each end for the valve cover. Hot everything re-installed and we had the same problem. Again I asked to see the tooling. The cutters were one RH and one LH. They had the carbide inserts for the other handed cutter in the side they were having issues with. Proper inserts, problem disappeared. All because nobody properly analyzed the problem to start with.

@@mpetersen6 I almost lost both my hands when a machine that was supposed be off suddenly clamped down on me. Turns out the day shift foreman had a suckass electrician bypass the switch and wire to stay hot all the time to keep production going. Then the foreman tried to write me up for working in an unsafe manner. Same foreman on days used to also run the tooling till worn out and out of spec. I worked 2nd shift so one day I got tired of changing tooling right at the start of my shift. I saved all the worn tooling and installed it before I left. The next day the day shift foreman started screaming at me as to why everything was out of spec. I told him in front of the general foreman that it was his day shift tooling and why was his last cylinder head within spec and my 1st head was not. He started to say something but the general foreman cut him off and kind of smirked at me and said don't do that again. I said OK and walked away. Another day in the life of a factory rat.

Doing my own heads gave me a greater appreciation for the guys who do it for a living and also showed me why a port job is so expensive.

Chevy small block heads with 1.94" intakes were machined to fit the 2.02 valves, if you didn't relieve the intake side of the combustion chamber you left a lot of power on the table. If you never tried porting, deburr exterior cast areas and get the feel and learn to avoid kick back and grinder shimmy. Then venture to the critical unforgiving areas like the valve seats when you have confidence.

Have you ever used fine brass screen material at the gasket on the intake ports for greater atomization? I did with what I believe was great results, no formal test.

At that point I couldn’t afford to fix it. It looks like your burn is healing well.

@@thecloneguyz - what that means, is that after most of the work was done, each port was checked to see if it's Cubic Feet per Minute flow rate was matched to each previously completed port. If the ports all flow the same amount, then during each intake cycle they will flow the same amount of air and fuel in to the cylinder, so each cylinder will make the same amount of power. If an engine is perfectly balanced mechanically, and makes the same power from each cylinder, it will idle with nearly zero vibration, and there will be less stresses within the engine as runs, so it will last longer and deliver its performance smoothly.

Hey Tony, I'm actually working on porting my own slant six head at the moment and I was wondering about the short side of the ports. In each one there is a small raised parts about the size of 2-3 pennies stacked on top of each other, they're about 3-4" inches into the port. I went ahead and removed them from the exhaust ports but I was wondering if I should leave them in the intake. It would seem to be an arbitrary casting flaw since it's in the intake and the exhaust but I was also thinking it may be in the intake port to kinda toss the mixture around and ensure good atomization. What's your thoughts?

Are you going to put a three angle grind on the valves? quick easy HP by doing that . Also,CC each chamber ,then adjust the volumes until you get them all as close as possible ( I have lapped valves to get the volumes all the same. Why ? It's just like balancing and the Engines so much smoother than if you don't bother . On pre 1980 engines you have to port match them as most castings were a bit rough from the factory . I did a set of alloy heads on the weekend from 1975 which were miles out .

On that back cut of the intake, before i suggest anything, i know flow is everything, but you are dealing with a thumb over the hose type situation. Ever thought of building up epoxy into that back cut? I know it might drop overall flow, but to straighten the flow, it might help it flow better. I've been a believer of smoother flow is better then overall flow. That back cut does the same as the ridge on top of the valves, you talked about in a past vid. I'd think smoother flow would do more than having a killer flow number but at the cost of restrictions

Oldbmwr100rs Yup, the best way to do it these days is send the head out to get CNC ported. Don’t have to worry about hitting the water jackets or making it worse either. People often make the mistake of polishing the intakes which is always a bad idea as the fuel will puddle. Aluminum heads are much easier to port and don’t take three times the effort of doing cast heads. Still stand by using the sandpaper rolls, much more control and you won’t destroy anything if you skip like what happens with a carbide tool. Plus they don’t jump around all over the place either. But yeah, porting is a art and so much knowledge has been lost over the years. These days it’s cheaper and cost effective to just buy aftermarket heads as they are superior to almost any older cylinder heads right out of the box.

The rule book gives plenty of instruction on building to pass tech. The very spirit of Bonneville is steeped in home built creations. They prefer mild steel roll cages with gusseting, MIG welded. SCTA and all the racers have a great time good for lifetime memories. If you pick the project car and engine choice wisely (this is what the rules book is good for) you may find a record that looks soft. Something perhaps around 180-220 cu. in. perhaps? Then see what kind of results you could achieve with a slant 6 either blown or unblown. Even if you never get anywhere near a record it would still get tons of views. "Blown" means any method of boosting from helix to centrifugal blower to turbo. You can build it to run on fuel and a nitrous system puts a car in a fuel class. Dry lakes and salt flats are under the aegis of sanctioning bodies that remember where they came from. This is why they actually prefer to see mild steel cages in cars. There is a potential problem i could see developing though. Uncle Tony gets hooked on land speed racing and installments continue regularly the rest of your active adult life.

Sounds good to me on the intake port head port slightly bigger than the intake manafold so there's no interference when the fule mixture leaves the intake manafold!!

How much do you think its beneficial to port the head in your case? Do you have any advice for my Renault11 (carburetted, 4cyl, 80hp) ?

Pretty significant gain with this head, but I can't say on that Renault. I'd ask around in the forums

theres a lot you can do depending on just how daily drivable you want to keep that trusty old six popper id smooth and open the oil return holes and smooth out the spark plug reliefs a little as well they can get tricky so i wouldnt go too far with them then have the head planed 010 to 020 for a slight bump in compression

Oh, how I DON'T miss porting cast iron heads! Did any of you ever weld them up with brass rods? Talk about work!!! But man, you could make some power if you were willing and able to do the work.

uncle tony- great job as usual. do you use a carbide bur or 'stone' to cut the material for porting? wtf happened to your hand? you didn't accidently throw a cigarette into a bucket of gas did you?

Were the intake ports undercut purposely to create swirl? Or is it just a shitty casting? Just curious. And as far as that under cut goes I would think increasing the size of the intake valve would match up that undercut and blend it all a lot better. I guess you'll find out how well it works when you get it all together. Looking forward to hearing it run when you're finished. I've seen some videos of those old slant 6 engines with boost kicking ass and taking names.

this might be counterproductive, but could you fill the runners with brazing material and then grind/sand them to better port match the valves so those undercut lips no longer exist?

Could significant gains be appreciated by adding metal to the undercut areas in the intake tracks? A little tig work and you’d be in like Flynn! Would that technique be just too much sugar for a dime? Also, would you have problems with head warpage from removing the stiffening ribs in the push rod gallery? You may have addressed this on the video you made, but I missed the damn thing, and I am too lazy to go find it🤨. Good work you’re doing sir👍✊

Can you use cast iron welding rod and fill in the undercut on the intake port? The new cast iron rod works well on cast iron. The intake doesn't take a lot of heat so I would consider using it. I wouldn't graze it because brass expands at a different rate than iron and might come loose and enter the engine, and you know what would happen next.

So is there a way to do a destroker to a slant? I know it's different but something like the 377 sbc...big bore with a small stroke makes an RPM SCREAMER...can you do the same thing with this slant to get some more top end out of it?

@@jerrytee2688 the heads were designed to be used in an under square configuration. They have only had minor combustion chamber modifications through the years. And that same head was on the 170 and 198. The 170 is capable of some RPMs, too. Even the 225 with the mile long stroke it has, is underappreciated for RPM capability, IMO.

With the bigger valves you can get rid of a lot of the under cutting and shrouding of the port.

I remember all the boys on the 1980s had to have the heads “ported and polished” and polished meant like a mirror..... Hours and hours of wet and dry sanding by hand Then they worked out it’s no point doing the polish on the exhaust side because the carbon still sticks anyway and stuffs up the polish.... and on the intake side they worked out a mirror polish was not the best for flow and fuel atomisation what was better was a mild coarse finish but still ported.... Something about gasses flowing better with multiple small ‘eddys’ rather than in a ‘laminar’ fashion.... and the fuel atomisation was a bonus.....! I wonder if that’s still the case?
