It's what Steve Weiner advised me to do, and I believe his thinking is that it'll give a "soft" limit with one bank of plugs dying at 7,300 and the rest cutting out just 200 rpm later, rather than a "bang" shutoff all at once.

Counter-thinking, for what it's worth, is that you don't want the engine running single-plug momentarily, especially under high rpm and load. But then I've never hit the rev limiter anyway; Rick Deman took it up to 7,000 several times when he dynoed the car, but that's the most it's ever done.
