I have a chance to buy a set of Aluminum heads. This is kinda screwey. The heads don't match. They are the same cc 118. Casting #s are 14011077 and 3946074. The differece is in the exhaust port. One is a C port and the other is a regular port.
First are these heads any good? I will be putting them on a 427. Next what are they worth? They have about 6 helicoils. Stainless valves.
Will these be a good combo on a 427?
