F22B1 Intake Manifold Options?

[tasty_chicken]

I've been doing research on a Intake Manifold for my F22B1. From my research people have said that pretty much that the IM on the F22B1 sucks (small ports, bad flow). So i'm trying to find a IM that would flow better. There is one guy on AD who swapped a H23 IM on to the F22B1 however, the ports on the H23 are too big and they aren't matched to the head.

So pretty much i'm wanting a good IM that would flow better, dual runner is a plus. Will the F22A6 work? Anybody know of others?

F22a intake manifolds will bolt up nice as ever but the port that carries the antifreeze to from the head does not match up and will leak. No choice but to stick with f22b1 IM or f23, not sure if H series work.
