On fuel pressure for carb..........regulated to carb between 6 1/4 to 7 1/4 with NOS i'd say on the higher side of the window. You want a constant pressure from the pump of 15 to 18 psi to handle the demand. Speaking of.....what size fuel lines are you running. Make sure floats are set correctly.
Plug gap.......sorry, not a NOS person. IDK.
