Don't know much about engine except its a 0010 block no other #'s. Should i get the 72 cc 180 cc or the 64cc 180cc. What size gasket? Thanks in advance

Need more info on motor ( cam,pistons etc.) and intake and exhaust and what you want in terms of performance.

64cc head = higher compression than 72cc
thinner head gasket = higher compression

Before you shell out significant $$s, it would be wise to somehow figure out what kind of pistons you have, i.e. flat tops, dished, 2 valve relief, 4 valve relief, dome, etc. Then there is the deck height to consider. All of these factors are crucial in making a wise head choice. Don't just depend on using gasket thickness for adjustment. It is possible that you could render the heads good combustion characteristic ineffective by using too thick a gasket.

I know this is not what you want to hear, but.......................

I would use 64 cc angle plugs and at least 200 cc
