Colder Spark Plugs Stop Pinging?

I live in a really hot, and high traffic area, my bike with a S@S B and .565 cams liked them better, so did all my over cammed and over carbed Mopars, PLEASE Don't think I am taking Your thread that way. They just seem to not get as gas fouled. My Apologies
No apology needed. Everyone has their favorite brand of plugs so no hard feelings at all!
