Buy a round gauge at parts store ($1) and gap plugs .003 more than factory spec,, file the electrodes square and then index them on installation. NO ANTI-SEIZE.

I also run the 1422 NGK's at .024. These are one step colder plug. Prior to going one step colder I ran the plug you mention ilzkbr7b8dg with it's stock .032 gap and had no issues. Mario recommended the 1422's at .024 with my stage 2 tune.
