415HP from 318ci IS POSSABLE!!

The reason that they also had to run valve reliefs in the pistons is because of the 2.02 valves. They tend to sit higher in the chambers. They also used Eddy's RPM's which have shallower chambers where the valve sits than the stock iron one too.

I don't have a clue as to who did what on that engine but, and I really don't care. But with a set of heads that flow that much and a roller cam that large should make a good bit more than 557 HP even on pump gas. Maybe they should change the cam to one that works better. Man we ran that fast with a 360 .030 in the 3,330 lbs duster that the 322 is in now, on pump gas. And it didn't have 2.02's either, it had 1.88's.

Your last sentence is actually more true than you think. I used my knowledge from the 8 + years of working with Top Alcohol cars and applied it to the small engines. Better yet check this out 5,042,440 # patent from back in 1991, from August 27 of that year. All you have to do is look up US patents and that # and maybe this will help you understand why my engines run so well.

What I do know is the fact that when Kurt Johnson first started racing he had these heads on his engine, it was in 1992 and the car it was in was Dick Scribners Torco oil backed Olds Cutlass. Needless to say Kurt beat Warren his dad in the finals. These were the heads that were on that engine and in that car.
