Has anyone used the Cometic MLS head gaskets vs, Best? The Cometic gaskets are expensive, but they come in various thicknesses and the bore size is smaller. I calculated the Cometic 3.86-bore gasket/w .040 compressed thickness to have a volume of 7.67 cc vs 10.00 cc for the standard bore Best. Wouldn't the Cometic 3.86 bore size be more than large enough for a cylinder bore size of 3.81? Generally speaking, shouldn't the gasket bore size be 0.030-0.060 larger than the the cylinder bore?
