this is true
you can get a spair head, some cartridge rolls, a nice die grinder with varriable speeds, a couple of flap wheels... clean out the rough spots and it will improve flow.
i wasted 2 heads looking for all the water jackets just so i knew how much and where i could take the most off for the best gains. in some areas there is only a couple of MM before the waterjackets... to thin and it will crack under system pressure and opperating temps/conditions!
