Hello, when I'm looking around for head gaskets everything I see is over stock bore... gaskets being offered, 92mm n 94mm, or sizes over 3.552. Why is that? Am I to understand the head gasket is supposed to bigger than the actual bore? If that is the case a 92mm would be ok yes? and 94mm would be bored over. or a 3.625 be ok as well?

 

bump...
