| Neither are comparable to C6AE-R or CJ. |

The C6AE-U and D2TE-AA heads are basically identical except the combustion chamber is shaped differently and the D2 heads got an induction-hardening process done to the valve seat area to form carbides in the iron in an effort to harden them cheaply.
Either head will work equivalently. If you think a bit of extra compression might help, go the D2 route. If you want the engine to appear stock to FE-experienced folk, or want to keep compression a hair lower because you're not sure ho the engine will handle pump gas, then go with the earlier head.
I'd probably lok at valve sink as the driving parameter. If one head has more deeply sunk valves, due to miles and many valve jobs, I'd stay away from them unless installing oversized valves to bring the valves back above the surface.
