all references i have ever read about head bolts, and gaskets use compression ratio as a guideline...but what about actual cylinder pressure??? now running arp bolts, felpro permatorque blue gaskets with 12.5 comp ratio. cranking cylinder pressure is around 220psi.dist is locked @ 37*. just burnt a gasket between #3 an #5. plan to go to a mls gasket with a set of studs, but just thought i would try to get some opinions. and it took alot of runs for the gasket to finally fail. any help would be great thanx!
