Most of the old valve grinders from the 1960s & prior have a set up on one end to face the stems. At least that way the facing is concentric and relatively accurate. I'd hesitate to grind stems with out some sort of similar fixture and a fine grinder wheel for a nice finish. Having a good way to true up the grinding wheel now and then is also a good idea. A person could rigg up a grinding set up if they have the means. Even a bench top disc sander could be utilized with some ingenuity. You certainly don't want to take off too much unless you have a valve seat grinder.
