fowled plugs

quickittyMember

I got a question about the right plugs.
My engine is stroked to 393, mid range cam, nothing wild (hydrolic roller) Estimated at just a hair under 500HP. Quickfuel carb.
I have been fouling plugs every 6 weeks or so and I don't drive that much. But I do let the car sit and idle for a while each weekend.
I have tried leaning out the carb as much as I feel comfortable.
It runs great in the higher rpm range, but as the plugs get loaded up it kicks and spits on the lower range.
Is there a plug I can use that won't foul as easy as the autolites? Should I run a hotter plug than standard?
Any suggestions?
