Just some simple stuff, getting rid of rough spots and smoothing out some sharp angles. Both intake and exhaust had kind of a ridge around the bowls about 1/2" down from the valve seats, so took care of that, and narrowing down the guides a bit. Not opening up the bowls too much cause I just don't want to spend that much time on it. And there may be some enginequest heads in my future, maybe a year down the road when I have more to spend.
