The rocker refacing tool for my Black & Decker valve grinder is stashed away somewhere- - - -haven't used it in years! I've found that a piece of 400 grit stick-on sandpaper for my 6" disc sander does a much better job of refacing rockers than the fixture for the valve grinder does. It just takes a little practice at following the contour properly freehand.
