I had around 8.5 to 1 with .042 thick head gaskets. I could only run 12 psi of boost with 93 octane. I put in a set of .078 thick head gaskets. There is a huge difference in power, at least a 50hp or so less. I can't turn up the boost yet because of oil being pushed out of the oil pan gasket/silcone. Does anyone know how to caculate the cr with the difference in thickness of the gaskets?
