nitrous spark plug

What is the plug that everyone likes the most for nitrous. I have a forged piston 360 with box stock eddys and an airgap intake. I ran a separate full tank with 110 in it and im using 34* of timing. I have the 150 jets in it now. I have 2 step colder ngks in it now. I only made 1 short pass in 2nd through 3rd. no detonation. but im super new to readying plugs. plan to go to a 250 shot but you know baby steps. any info would be helpful thanks. Mike k
