N2O Plugs and Gap?? I am new to Nitrous and am close to finishing my setup. I will be running anywhere from a 75 to a 125 shot on a stock LS1. I have a Nitrous Xpress Wet System and Im trying to figure out what heat range plugs I need and what gap to set them to. Open to suggestions and explanations on how to determine what what heat range/gap to use. Thanks!!

There are some people that will say you would be ok with the BR7 on a 200 shot.
Personally I would use a B8EFS.
After the BR7EF, NGK does not make a resistor style plug so the 'R' denotation is removed.
The -8, -9 heat range taper seat plugs that our stock head cars call for from the factory are just designated as B8EFS and B9EFS, no more 'R' denotation in the designation.
Hope this helps. I would run them with the gap they have out of the box which is close to .026-.028 IIRC on a B8EFS.
