Here's a little how-to I made when you get around to taking off and putting stuff back on:As for porting, you're going to port the ends of all the runners. Best tool is a Dermel. What you want to do it port the bottom half to till you get comfortablly close to that green o-ring. Porting the top half doesn't do anything because that lip in the top part of the runner is for the fuel injector, so that would be retarded. Is you have a 65mm TB (or 70mm), your also going to need to port the top on the manifold so you won't have any interference with your butterfly and it will just make it flow better since your matching diameters a little better.
