Intake manifold

So I have mentioned it a few times I have a 383 I'm stroking to a 496. Short block is going together but I'm having a problem with intake selection I have the trick flow track Heat but I wanted a dominator flange intake manifold that I could port out and match up to the trick flow Max wedge 270 heads. I ordered a Indy 400-2 from mancini upon their recommendation but it is only a 4150 Square bore and I would like a dominator flange intake manifold are there any suggestions of what I can do?
Hopefully positive and helpful
