what spark plugs
 

I have a 350 with 9.5 -9.7 comp, perf rpm heads, 284 2h cam and headers. What plugs do all you experts reccommend. Its also running a edolbrock carb, and perf rpm manifold.

I have tried most of them..... Bosch, ect, ect, but in my opinion, the ones that I could actually feel an acceleration with are the AC Rapidfire plugs. Gap to .045

what i really want to know is what heat range to run.

anyone??
