I was hoping you would chime in. After comparing pictures of mine and some of Vizards I don't think i'm ready for the cartridge rolls yet, lol. When you say streamline, do you mean taper the guide boss into the runner? Also, I read somewhere about not taking very much at all from the back side of the boss. I have looked at your profile pictures and didn't find any but do you have a picture or two of a completed exhaust port that you have done? Am I right by not messing with the intake bowl? I really do value your knowledge.
