10.5 housing
just bought a 10.5 housing for my evo 8 and i was courious if it was safe to take it to any machine shop to get it ported and polished. is this a universal thing or does the shop need to know the tolerances of the housing? is this worth doing first of all? i was also thinking of doing the stock manifold.
