Hey Group lets look at the obvious about wether or not a plug will protrude enough to clip the seal. Measure the distance from the seal surface to the end of the sidewires of a standard plug. If the new plug isn't any longer it cant hurt the apex seals. Heat range is another story all together.

So, I am guessing by this thread that it is ok to use the none shrouded stock NKG plugs. I have not looked, but now assume that the more standard type automotive plug fits even with it longer electrodes extending further out.

Bill,
You are correct................You have to look up the AR2592 plugs by part number............This plug
is actually used in some early Chevrolet and Chrysler Big block engines for racing..........
