Non projected plugs for nitrous? NGK?

[67Charger]

What is the part # for the non-projected NGK's for nitrous? 5.9L Magnum with a hughes steamroller cam.

You didn't say how large of a nitrous shot but for a rough generalization these are 2 steps colder than a Champion 12 series

2-1/2 steps colder than a Champion 12 series.

And these are three steps colder

I say "generalization" because whenever I've cross referenced NGK's heat ranges to other makes they tend to have a broader range. However, that's also been the projected tip plugs.

Ngk 4554 is a -8
Ngk 5238 is a -9
Ngk 5820 is a -10
Ngk 6596 is a -11
These are non projected 3/4 reach plugs with a gasket seat.

4644 is the bkr7e, thats what most forced induction guys run on the magnums.

6962 is the bkr6e, standard na plug.

5122 is the non projected plug. Br7e,

Ok, so if the force-fed crowd is running just cooler than stock projected-tip BKR7E's, at what point do I need to switch to non-projected for N2O? I've got the plate setup for a 100 shot, and don't plan on passing a 150 shot. First hit is a week out.

bkr7e will be fine for 150 shot.
