I like these D0OE heads alot. Have ported and modified them as you are doing. Tried a set of mildly ported GT40's and lost power so went back to these using 1.90/1/60 valves.
@terrygrover6440
2 жыл бұрын
Im surprised you'd lose power considering the GT40s are pretty good but don't forget the early heads have a combustion chamber 55 to 58 cc so you might of lost a point of compression but i am fond of the early heads myself my plan is to see if they will out run my e7 ported heads which they should do but will see how that goes.Happy Thanksgiving

The compression loss was part of it, also the 70 302 heads were highly massaged. The P head with the smaller chamber might have been a better choice.

@@rondye9398 The Gtp heads would be a lot easier route to do what I'm doing especially since I have a pair almost done, I wanted to do something for the guys who have the old school heads just to show what you can do with them but these are gonna be blown out further than most people would be wanting to put time into and they will be in the danger zone as far as being thin and also will contain epoxy by the time I'm done with them 👍

I recently reworked a set of D2OE 302 heads I had laying around. hardened exh. seats, new guides, cut for screw in studs. with the valve job I use a set of mid 80's 305 chevy valves, 1.85/1.50 so the intake is same as a 351W early valve the exhaust is just big enough to cut in nicely and get a throat cut. I was porting the exh bowls and cut through one due to core shift, have a buddy hot braze them but not sure they will work. be careful and look for core shift! throat I don't go more than 88-89% of seat diameter, early 289 heads seem to have less core shift but the late 60's/early 70's 302 heads seem to have more. I have seen about 5-10 sets of each so not a huge sampe, your mileage may vary as they say! I have 3 sets of early 289 heads, I actually put them on a mill and roughed out the exh opening, went a bit too far on one but can be fixed up. ended up installing a set on a 302 for a mustang II/4 speed. mild cam, 1.90/1.60 valve package and an rpm intake & headers. that thing would really just burn the tires off in 1st & 2nd. love doing the portwork, cutting on iron please please guys wear a mask, N95 or better, hearing protection & eye protection. your senses and your lungs are worth it. now, back to a set of 351C 4V heads that need the bowls blended!

I still have a set of 69 58cc heads. I thought I'd use them but I doubt it. They'd have to be completely reworked and that's expensive nowadays and frankly if i was worried about that half a point compression between them and E7 I'd mill the E7 down up to.040 and then I'd have that half point. Or different pistons. If they were Australian Ford heads I'd be thinking differently.

Stock those exhaust ports flow about 113cfm after some good work they flow 175. Your flow logic is correct for high rpm race flow. I would like to know how thin you push that casting with no cracking issues. Thanks, Charlie

Will find out so far I've been very fortunate pushing the boundaries my problem is I am determined to make a head do what I think it should do I know in the porting world that's not logical I do envy people that have all the tools and machinery they need to do these heads, because I always have to wonder and guess and take a stab at it how much I left on the table like with my e7s Im not a flow number person but in the flow number world when I ported these heads I thought I probably left about 40 cfm or 20 to 25 horsepower but I had no choice we needed them on the car in a hurry at that time ,I'm hoping to pull them back off and go over them again. Happy thanksgiving

From what I know all the smog bumps that I've come across are removable due to its usually done with extra casting but once you remove it most of the time the casting will be thin in that area but I'm not familiar with your heads investigate further and make sure it's not a hollow casting, good luck with it 👍

There fine depending on what you're trying to do but they have a larger combustion chamber from what I remember which make you have lower compression but you can make any small block Ford head make 3 to 400 hp depending on combination such as cam , intake and compression but I would use those heads if I had them, but I would mill 20 or 25 thousands off of them for a naturally aspirated engine, thanks for watching

The casting number identifies the head & tells you the first MODEL year they were used. D0OE heads would NOT have been used on a 1969 MODEL year vehicle. C8OE-J, K, L or M, C8AE-J or C8DE-F or the C9TE-C truck head would have been used on '69 MODEL year vehicles. The date code will tell you when specifically they were manufactured.

Gary this is how I was taught to identify these heads, Im not worried about what they came off of or what year vehicle Im not number matching a head to a car Im just worried about showing the numbers that most people are accustomed to, everyone references the heads this way this is what we look for when looking in the junkyard for a pair of cylinder heads
