I just bought a Blox turbo manifold and it looks great but I was wondering if I should port and polish it so that the runners go smoothly into the turbo.

#1 has a smooth lip about a 130 degree angle into the turbo but the other ones have more of a 100-110 degree angle from the the runner into the turbo

Would I be able to make more boost with all the angle smoothed to a 130 degree angle
