... What I'm doing these days is ordering the Trick Flow intake from Hughes Engines with their deep port match already done. That way I don't have to mess with it. Hughes has a CNC program on hand as well as the correct fixture so I don't see any reason to eat chips on my bench when they have it figured out. I highly recommend using the Hughes deep port match even if you're planning on doing some plenum work yourself. Might as well get the dirty work done by them and just do the fun stuff yourself.
