NGK plugs & nitrous?

Does anyone run these plugs (BKR6E-11 "2756"), talking with a few, i was advized not to run a "projected" noise when running nitrous, These plugs are 1 heat range colder & the nose isn't as projected as the Autolite 3924s that i run now, this is for a 95 360 magnum. I'm only hitting it with a 125 shot, but may go 150.
