Compression ratio and head gaskets
So the new heads will be 64cc and I still need gaskets. Supposedly I will get .5 bump just bolting the heads on then I found this:
With 64cc chambers and .056" head gasket SC=10.61 DC=7.91
With 64cc chambers and .040" head gasket SC=11.04 DC=8.22
So if I use the Cometic .040's I will have 11:1. How much power will that net realistically? Trying to judge if the $140 over MLS GM's and possibly having problems running pump 92 would be a problem.

Realisticly about 10hp.
