Dan;

I'm running the same plug or maybe the RF18YC,can't remember right now with great results.BTW,also running MSD and a .040 to .045 gap....

Tried the platinum plugs and was not happy with them,they seemed to foul out real easy and quick....

If you find something your motor combo likes,like these plugs,stick with them....

Also,local guy with a dyno has told me many times and shown me a few times that switching to Champoin plugs regardless of engine make or size 95% of the time results in a 2 to 5 hp gain on the dyno...do not know why,but I've seen it. At first I only ran Autolites and then after seeing the proof I switched to Champoins and find they last longer and burn cleaner,you'll never be able to tell if you picked up 2 to 5 hp,but my engine seems to run "smoother" with champoins....

Just my .02 cents......
