Spark plug gap

I'd look through modularfords but they're down...

I've got a 94 and the nitrous is going on this weekend. I'll be running a 150 shot eventually, I'm starting with a 65 shot. So I'm running Autolite AR94s, which are 2 heat ranges cooler than stock. What do you guys reccomend?

I ran mine at .035 and they seemed to do well. More info on the nitrous setup please

My friend ran a .045 gap on his LS1 running a 175 shot for years with no problems.

It's a Harris speed works dry kit, for which I paid $301 shipped. I'm thinking of running a hobbs switch to prevent it from spraying if the fuel pressure is low but I'm not sure where I can find one that will work with fuel (finding plenty of ones designed for water/alcohol injection but I'm not sure about fuel..)

Anyway, on the 4 plugs I replaced (I'm doing the other 4 this weekend as well) I'm running a .028 since the plugs came that way - for now.
