I have a set of heads from a 427. Where the ford casting number should be there is 2143, which dont sound like a ford number. The intake with them is a C3AE-9452-J and has 2 4bbl hollys on it. Any help with the heads would be great.
Those are 1959 FE heads from a 332 or 352 also used on the 361 Edsel in stock form they had 70-74 cc chamber with 2.02" intake valves and 1.55" exhaust. Not a very good match for a 427 8V.
