ok i ported the manifold and i must say that it was a mighty dirty job. and my back hurts from bein bent over unboltin and reboltin. i expanded each port considerably, not a great amt, maybe 1 mm all the way around each side, smoothed it out, expanded the hole that runs into the cat, cleaned and smoothed it and my car still runs. butt dyno measures no gains but i dunno. only took me about an hour to do. its good knowin i cleaned a **** load of carbon out of it. i shoulda got pics, damn it just dawned on me. sorry guys. but its done.
