As stated, they are the same head, even the valve size for that year. It is not worth anything to buy TA heads even if You could find them, they are "J" heads that simply
had the pushrod holes drilled offset out to enable wider porting at the "pinch", which won't give You squat if You don't do a lot of port development elsewhere first.
I disagree completely that it wouldn't help much to install 2.02's with a proper bowl-cut blend & valve-job, but You really would have to weigh actual costs there, ??????
The upshot is, nothing lost & nothing gained with Your combo other than You picked up 20 cubes, ...& whatever actual difference in compression was & is between the 2..
