actually you dont want it that smooth though. at the most you should have went about rough , med then an 80 flap wheel which will actually give you a pretty nice swirl effect if done right. if you didnt use gaskets your pretty much set as long as you didnt hog it out. hope you didnt take too much of the port floor you can almost leave the port floor alone. you can further take this process alot more if you want.
port match the intake manifold to the head. and port out your exhaust manifold. no port matching to the head. but not too bad though. ill be porting a buddies 300ZX twinturbo upper and lower plenums together so i can post some pics or you can check out my home page
