Need some help id my cylinder heads in my car its a 68 302 block so I was assuming it would have the D80E heads on it however when I pulled them the other day after starting my rebuild the only casting number i can find on them is inside near the valve springs there is a plate with a large E on it and a smaller one with 9F14 I do not see any other casting number on them anywhere just wondering what these came off of so I can get the parts ordered to rebuild them if anyone can help I tried the Decoding Ford Parts numbers page by google but it sorta made sense but not with the number I found can anyone help me!!!!!
