Suggestions on which plugs to go with

I have found that champ’s always worked better than other brands I tried except for a set of accel plugs I tried. Those worked as good.
Generally the higher the compression, the colder the plug, and I’m sure there is a whole lot more to it than that. Best to stick with one brand and keep trying different heat ranges till you find what works best. I would start out with a stock heat range plug or one range colder. Then again that used to be easy when plugs were stupid cheap in the 70’s.
