Stock LT1 ignition often have trouble ~7 psi.
I have run an MSD box on 4 boosted LT1s and have had no problems to ~20 psi. I use autolite I think 106 (whatever they call for stock) and run .030 - 035" gap
Good luck

A little bit of info would be helpful here...
What 2 plugs?
Did you change them and it did it again?
Did you change the wires for those plugs?
Swap injectors to different cylinders and see if the fouling follows?
