I'm running rapid fires right now, but I'm gettin ready to install headers. I figure while I'm in there I might as well change the plugs. What's everyone runnin, what heat range. I have a MSD 6A if that means anything. Thanks for the info !!!!

 

Im using ngk tr-55's. Do a search on these plugs you'll see lots of guys are using them.

 

either the ones mentioned above, or the stock AC delco ones are good as long as you arnt running N20

 

i've tried about 5 sets of plugs i've had the best luck with the stock ac platinums it calls for
