These pictures are of an elliptical valve job done back in the 80's by one of the top Pontiac head porters. The top cut mimics the bottom cut just not as pronounced due to the small top angle.

Thank you for the info, I know it was printed somewhere but very little info on it. I had talked to him about it once but it was very long ago maybe late 90s. Figured someone had to have some info on it. David visard has mentioned it before also he also mentions a mod he used for reversion on his mini copper that gave him a much wider power band .
This isn’t for one of my turbo cars they dont care much about head work it’s for a NA set up. . Which sadly I’m just not that well versed in anymore after turbocharging for so many years
I used to race NA w quadrajets and I can hardly remember anything from back then. I do boats , 2 stroke outboards, airplanes lycoming mostly, 2 stroke yamaha jetskis supercharged 4 stroke seadoos, , dodge deisels , it all gets confusing after a while . Too many directions
Either that or I’m just plain getting old .
