I think that my 1961 292 has the original heads on it but I am not sure because I don't see any casting number on them. Would the 113's be the most likely heads? The engine is all together and in the car and I have scoured every inch of the heads with a mirror, including around the rocker arms but no number. Where should I look to find the number? Thanks, Alan S. Freeman

If the heads are original to the engine, then look at the head under the intake at the front water ports for the casting number.  COAE and C1AE are the two head castings that come to mind for the 1960-1962 car engines.
