Would need to know the ccs of the heads and I assume it is std bore. But I took .030 off of my J heads (ending up with 64 cc, found my machine shop slip), used a fel pro .039 head gasket and ended up with 9.8:1 so Im guessing you would be rite around there if not closer to 10:1 with the thinner head gasket. I wouldn't go through the hassle, just sell it to me. HAHA!!
