I'm going to maximize both for what I have, yes. The block will get decked .055" for zero deck height. Pistons have a 14.5CC dish and heads are 59-60CCs. I woulfn't mind finding a thin steel head gasket, but not a deal breaker. With a .040 gasket I get like 9.1:1 which is about where I want to be. I didn't want to end up with 175 PSI cranking pressure like this engine I am running now.
