ET 215's. Help calculating my compression Hey guys, need some help. There have been no mill to the heads yet. I have .075 out of the hole using .045 cometics. I verified my clearance and I have alot on the intake and about .192 on the exhaust. What would my current CR be? If needed, how much could I mill and be safe without fly cutting. The cam is a monster and I can't believe I have this much clearance available. Thanks in advance!
