Has anyone ran an engine with a thinner head gasket? Im thinking of ordering a set for my S13 1UZ project, but im not sure how much the CR is going to change and/or if im going to have any other issues. Anyone have any thoughts, ideas, experiences?
I guess cometic gaskets will lower comp alittle??
But why not machine heads while they are off??
Then I'd check piston to valve clearance....
Yes it will change cam timing alittle....
