    SOLD I just acquired a nice set of rebuilt gm heads on a trade for an engine I had. I don't know anything about heads but what the specs are from googleing the casting number. They are for 283-400sb. Specs are 1.94 intake valve, 1.5 exhaust valve, 74cc chambers. They look well done.Not sure what...
