Help with Identification

Guys Thanks I know you get tons of these request.
A moment to introduce. I currently enjoy the Jeeping aspect of motoring hobby
As a teenager I built a 69 Mustang fastback Mach 1 interior with some help from a couple of ford mechanics using a 410 CID 390 gt heads I think I had a crane cam about 480/500???? lift and 270 duration Eldebrock intake and Holley 780 backed by a C6 and 9" with 3.50's honestly as a kid it was a screamer sadly too much of one and I wrecked it.
When I first aquired the 410 and disassembled it it had two different heads on it one C8AE-R and a C6AE-U and a Ford aluminum intake with nothing other than the FOMOCO and firing order on it. It is a fairly low rising manifold with the EGR provision in the back.
I still have the heads and intake and would like to know if they are worth anything or are they just scrap???
My son is looking for a '67-'72 pick up and they might end up on that if they are worth matching. The head obviously have different port dimensions.

Thanks for any help:confused::)

The intake is certainly worth keeping. Look for a mate to the best of the two heads, mismatched heads are a no-no!
The R head is a "special racing" one, it's probably the better of the two, though I have no listing for a U designator, maybe a factory replacement head?

I would say the R head is a C6AE-R not a C8AE-R. The C6AE-R are the larger port lowrisers. The C6AE-U is the newer velocity port (smog) design w/smaller ports. Could have been a mismatch from the factory or just a replacement somewhere along the line. 66 was the change over year from the lowriser heads to the newer smog heads. Intake sounds like a early aluminum lowriser version. I'd look for another R head and let your son use them with the intake. Those heads are pretty common and somewhat easy to find. Better than the C6AE-U heads too.
