LOL, the most I EVER do to a plug is to trim the ground electrode back just enough that the tip of the ground electrode is offset from the center electrode so that the gap is there instead of directly over the tip of the center electrode.
Just old school side gapping, like many before me did for years. Oh, and I usually index plugs, even when I don't need the clearance. I don't really make anything custom, but I do often try several different things to find out what the engine wants.
