Does anyone have any information on these heads I believe they are factory Ford could be wrong they are 21 stud I have heard of high compression heads but do not know how to confirm, my concern is if there will be an interference with the valves on an early 38 21 stud motor.

these would have to be 37 heads so there would not be a problem with interfearance with the valves. best to check it out with some clay. I have never seen non ford heads with ford part numbers such as 78-6050 Early 37 production until Feb 37. then again I have not seen any marked "Mfg. USA " If they are of Ford Mfg. they should have the P/N and Ford script, the script may have been polished off the P/N could be raised or indented. I think you have one Ford and one aftermarket.
