My friends '05 recently chewed up an intake valve. The valve sealing surface is cupped and the angles on the valve seat are somewhat mashed. He is replacing all valves with Kibblewhite and the rest of the valve seats are in good condition. He doesn't want to send the head off and there aren't any good engine building shops nearby. I have been researching the procedure for cutting valve seats and I believe it is something I could definitely do. However, I have found very little info on hand powered seat cutters and grinders. Does anyone know where I can find the required tools to do this job?
