That's an awfully cold plug. I use -9 NGKs gapped around .028".

I used to run NGK 7's on my 10:1CR 340 iron headed motor with a 150>250 shot and gapped at .030 thou with MSD6A, 36 deg total with 98 octane fuel over here, did have a seperate blue pump and line for N20 fuel only, never tipped a plug, ran sweet.
