Iskenderian makes a cutter that you can rent from them in many different sizes just for that problem. You put the cutter in the valve guide and turn it with your drill motor, so that the cutter is exactly where it needs to be, unlike cutting the reliefs on a Bridgeport, where you could make a mistake.
