Quote from post #7 by Ken: "They would be made exactly as My originals. 1-3/4" primaries, 2-1/8"(??) secondaries,2-1/2" no flange collectors. Fitment is round port 64-77 A bodies,75-77 X bodies, 69-77 GP and 70-81 F bodies".

I can't speak for Ken, but the tooling for these headers are for the round-port heads and I doubt you'll see a D-port version.

I hope I'm wrong, but I doubt it.
