The *main* reason that for _many_ years there was little to _no_ aftermarket support in the range of basic street-strip ( as in, not _all out race,_ ) Mopar cylinder heads is because the factory head designs are generally actually good enough that you can easily _make _*_good_* power with just some basic massaging of many stock castings!

Good evening Charles , update on M.I.318 from Mr. V. Was welcome and of course entertaining . He spoke highly of you and I hope that gives you some fulfillment . (And Money) Many people inquiring UTG live feed about the project and my take is U.T. has control issues mostly because he doesn't know you . I'm sure when this thing gets to the dyno T. and a lot of other people will be your long lost Brothers . Haha . Please keep the Spirit . Peace ✌️.

The small port heads I completed were 205 @ 0.300" lift, but petered out at 235 @ 0.500". They were phenomenal on the track, however. If they didn't go to leaking they would still be in service. We used a 1.92" intake valve.

Looking at that intake bowl there is some real potential there , I'm thinking tear drop the valve guide with the tip of the tear drop at about 7-8 o'clock toward the spark plug boss. Then with some cylinder wall side bowl biasing, swirl could be induced to make up for the fact that its not a quench head and u can improve combustion efficiency that way .

Another good video Charlie. One thing that I have noticed that is lacking on KZitem is technical discussion on air speed analysis in relation to porting. Everyone talks about the importance of air speed, and what the air speeds are, but no one ever says, I have a high air speed here, so this is what I think I should do. Likewise, the same for low air speeds. I for one would be interested in hearing your thought process on how you personally analyse the numbers. Now I know that it is not cut and dried, but I wasn't able to find one actual video on it last week. Regards Greg
