moving to a larger blower so going from a MLS style gasket to a copper with o-ringed block/heads. I’m currently at 10.6:1 compression running a 4.584 bore .053 compressed MLS gasket with a 14.50 cc compressed volume. The copper gaskets come in a 4.57 bore .050 thick (13.795 cc) or .060 thick (17.106 cc) compressed. Assuming the .050 was the way to go just not sure how much that raises my compression...didn’t know if there was a formula to figure it out. On a big block Chevy with 4.525 bore and 4.25 stroke.
