1255031 is the actual production LT4 Manifold that was on the LT4 Vette
12550630 is the GMPP version.

Ports and plenum are the same as the later LT1 intakes, just has more material above the port to seal to the taller LT4 ports and would allow port matching.
If LT4 intakes are expensive material can be added to an LT1 intake to make it work just fine, have to weigh the costs or each.
