Thanks for the info. I'm going to check out some local pick-a-part wrecking yards. I'm sure I can find a set of 302's. What is going price for basically a "core" set of heads? I'd like to go to a 11/32 stem valve and increase intake and exhaust dia. But that starts Adding $$ up qucik witht he extra machine work. Kind of defeats the intent. But I'll port match, and blend the bowls. Maybe have them surfaced. Run the thinner head gasket? Should work better then the stock 76 318 heads. Josh-
