I need help with a motor I bought. It has .250 dome pistons and my 64 cc heads that have been milled . 100 raisen eighth inch when I turn my motor over. Is it going to do me any good to change heads get a thicker headgasket, and index my plugs. 72 cc heads? Help me out I have the sb built and need to get some heads on it so I can race this weekend.

DMS That was a bit hard to decifer. Is your pistons hitting the head?? IF so thicker head gaskets might help but I would clay EVERY cyclinder. else Go digging around an old machine shop today and start asking about some 487 heads. Try to get the X heads. You may get lucky and find a set of 441 heads. If not go with the 882's.
