I have two sets of heads outside trying to figure out which is which. I have one set that says C7AE-H I think the last letter is H cant really tell. Then I have another set that says C8AE-H if anyone can tell me which motors these go on that would be awesome.

 

C7AE (check the last character) - 1967 FE motors, generally 71-74 cc combustion chambers.

C8AE-H 1968,69,70,71 motors, 68-71 cc combustion chambers.

The C8 heads do you know what motors they came on I think they are off a 390
