Paul, some of the "competition grade" tappets have an oil drain hole
drilled as you describe. They are fine as long as the surface that
rides against the camshaft isn't pitted or damaged in some way. It does
indicate that they are not original, or if original that someone drilled
oil drain holes in them...
