Bill J.,
   Good common sense observation.............Concerning the heat range the AR2592 is fairly cold so
early plug fouling is the worst that can happen...........Should that be the case then there are 2 other
plugs of this series (AR2593 and AR2594) that are hotter heat range............

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..........
