I don't think high power hurts plugs internally that much. It just erodes the eletrode & ground strap much quicker. Never heard of a ohm/resistance meter test for plugs? Maybe, not sure?

I cured the same problem by installing a new power valve.

I have a complete MSD setup, no problems with too much "power".
In fact Ive been led to believe a nice fat spark keeps the plugs from fouling.
My bad power valve wetted the plugs so bad it ran like a pig when idling.
