As far as the AE8x series:
AE80 came with the 2A-C
AE82 came with the 4A-C
AE82 Twin Cam came with the 4A-GE
Only the Hatch and Seca came in Twin Cam.
don't know the AE9x series well enough to be certain, but from memory the 4A-GE was an option on the CSi, so AE94's only.
Going from the differences in the head gaskets i do not think the heads are interchangable,
