Alright here the setup:

D16A6 block and head
P29's (d16a1 pistons)
D16y8 Head gasket
head milled two thousanths

My friend wants to know the compression...i want to say like 12.4:1, but i don't know how to actually calculate it and i wanted to get some other ideas

 

don't say I never gave ya nothin'

11.14:1

I used oem zc deck height since thats what it would be. I used .035 for the head gasket thickness because you said he got .002 cut off the head and in essence its like taking that much off the gasket, and i use d16a6 for the head and displacement etc...
