Im basically rounding down any sharp corners, trying to make the alu around the steel seat meet the runner walls as flush as possible(kinda hard to explain what i mean with that) getting rid of all the rought casting lines and high marks. 80 grit in intake 120 in exhaust tring to focus a some on the short radious spot and tried to keep a spiral effect in the intake as well. went ahead and started polishing the chamber as well. Why not?
