Should I do 1.800 comp height pistons and then deck the block so it’s true which these pistons are around 9.7 comp with 64cc heads. The heads I have are 65cc closed chamber and then I’ll use .039 fel pro gasket for its reliability
I'd go with that cr that works with cam and gasoline choice and the piston has to make that cr with whatever head your gonna run, and maybe keeping in mind possible future upgrades.
