Yeah, I would definitely suggest a non-projected tip plug like the NGK 4554 R5671A-8 (the -9 is probably too cold). The plug you have with the long projection would be an issue. Below is the R5671A-8

Nitrous works well if you feed it plenty of fuel and bring back the timing; however, since the nitrous is an oxidizer, it will consume whatever it can find if you don't feed it enough to keep it happy (i.e. spark plugs, pistons, etc).
