340 Intake manifold recommendations

I took the M1 back to Brian at IMM. He has a performer he can clean up. He van put a 100 bucks in port work to it and that way if I decide the TQ and the performer are not a good match I can use the airgap and 650 edelbrock I have on the 318. Just wanted to save the airfare for a future 360 I plan to build
