My 202 valve eddy heads that were lightly debured and cleaned up ran 9.87 . Trick flow heads with my same rockers and springs ran 9.78 but that was with a little bigger cam and a 950 carb versus the previous 850. I was hoping for a little more as we all do.was close to 5 k to gain a tenth gets harder to go quicker when these cars get to this point so I will be happy with what I have out of this 340 for next season as is lol
