ok guys im getting myself confused here and would love some help or guidance.

ive got a set of 806 heads stock cc when purchased (already ported and polished runners) i had a valve job done along with milling to 11:1 compression.

so my problem lies in my math to find what my CR will be with stock head gaskets and im also trying to find a starting point at which to find correct pushrod length by figuring out how much was taken off the heads

so for every .006" milled that = 1cc lowered
stock 69cc chambers taken to 62 cc for 11:1 = .042 was shaved off
stock gasket thickness is .052 or .056 compressed?

either way im looking at just under 11:1 unless more was taken off the heads or i use a .040 gasket. and my starting pushrod length would be around 7.350.

something just does not seem right about this lol

thanks SOMbitch.

i was actually looking at that graph and to me im getting that every 5.6cc = 1CR and every .006" milled = 1cc so then would milling .0336 = 1CR? this is where im getting confused lol. im not really after just answers, im after HOW to find the answers

Yeah, you need to measure for pushrod length.

ive got a pushrod length checker on order from comp cams and i just picked up some molding clay this afternoon. im looking to see if the math is right or if im off by a few thousandths
