The 2.8 & 3.1 heads are the same. The difference between the 2.8/3.1 & the 3.4 heads is that the 3.4 heads will have better valve train (being newer) and I've heard a bigger seat for springs.
Avoid 82~84 2.8 heads as these have the smaller vales. The only ones you should look for are 84 H.O heads (same as the 85+ MPFI heads) thru 953.4 heads. All will interchange.The bastardification of Third & Fourth gen cars.
