Crom Marine / MD1 head gasket

Don t forget there is an MD1 and an md1A I think the MD1 only has 4 head studs but the MD1A has 4 big head studs and 2 smaller near the push rods. The bores are different and so are the head gaskets. Be sure to order the correct one. The Thai ones are to the original spec and seem to have more resiliance than the later ones.
