Stage 2 headed guys ?

[Otto J]

I pulled the plugs out of a buddies car with a stage 2 motor, It has Champion S59C plugs in it.

Was wondering what the recommended plug gap is for these motors running a stock dis ignition system. It seems as though they are at a real tight .020.

I am replacing them and curios if they are supposed to be this tight.
We are running a 76Qtrim turbo in the 30# range

I was runing something like .028 on the Autolite 242's. That was with an MSD 7AL/trigger setup and single coil/pickupless dist.

Maybe you should open them up a little? Im not familiar with that plug, what kinda heat range?
