I went as far as i could without having to build a bunch of special fixtures. Then clean up my sins with the die grinder. The mill saved me hours. I also smoothed the runners at the unused plug boss on #8 and the 1/8-27 npt plug in the bottom of the plenum with some epoxy. I am uneecided on which direction to go with the intake. Whatever happens I'd like to keep the stock hood.
