Exactly! So I guess it will remain a mystery if it started it's life in a corvette. The heads don't have any of the typical high performance markings on front, but early 230 hp corvettes may not have had those anyway. The heads may have been changed, but probably not. Would they tell me anything?

Oh, and can I tell anything from the exaust manifolds? They don't look like their anything special, but they could have been changed to fit into the Ford.
