cylinder head id need help

[bdydrpd88]

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!!!!!

The casting number should be on the bottom of the head.

D8 = 1978+

Don't know why 1978 heads would be on a 1968 block. Maybe you meant C8OE.

C8 = 1968+

9F14 = June 14, 19_9
