A friend of mine just gave me a 18cc head and flywheel, now I wanted a 14cc real bad, but hey the 18cc was free. Now What will be my compression if I just bolt the head on with the gx200 head gasket? and how much do I have to mill to get the compression of a 14cc head with out a flat top? And last do I have to shorten the push rods if I mill the head?
