78-79 have better (larger diameter) heads and wider intakes, but compression only at 8.5:1. '80-'83 have smaller diameter heads and intakes, but higher compression (8.6:1 for the '80, and 9.3:1 for the '81-'83). The '83 has a different and possibly more robust block, which was the basis for the 3.2, IIRC.
Both variants of the 3.0 are very good engines. Either should work well with Webers.
