You dont really want to port match a street car, there are a bunch of things that hacing a step between the intake manifold and pulses from the valves closing and then the pulse bumps back to the valves it actually acts like 1lb of boost I dont know its confusing so just google it. Port match is only good for full out drag racing, but i think with your motor and built bottom end I would say just just put a b1 head on it and run it like that. I have seen A1's hit 350 on a volvo t3 turbo, so I think your 50 trim should be able to push that. Did you look at the flow chart to see where its most effective?
