Are there any aftermarket head gaskets suited to boost with the m42?
I've read the standard CR is 10:1 and a friend of mine is running a forged 10:1 f4r at 330hp safe however I was thinking a slightly thicker gasket would drop it a little and be safer. I only plan to run 10-12psi with a positive displacement charger
