Yeah, I thought they could deep port match it to max wedge? My mw ports are not much bigger than the TF270 int port. There was a mopar engine builder near me MRL, used to hange out on A and B bodies. He built a guy a 470 with cast 440-1 heads, used a nonport matched standard port intake. Made over 700hp. Didn't seem to hurt it. Have you performed any studies on what's gained or lost on port matching vs not? Curious
