Michigan	If design intent is 3/4" reach, which I think most of us would probably agree on as a 5.2/5.9 magnum head, I believe I would not want to stick future users of the engine with an oddball spark plug, and I would want to correct the machining error by spotfacing the spark plug hole to the proper depth in order to use the intended spark plug.
