ISTR that the plug is indexed to the intake valve to cool the plug with the
incoming a/f charge. As for spark plugs, I don't know what the racers are
using. I use NGK BP6ES in by street TR6/GT6. HTH.

I was curious as to what spark plugs everybody runs and favorite gaps.
I'm playing around with index washers now and opinions seem to vary on that
subject.
It's been said that it's best to index the plugs facing the exhaust valve,
between the valves and toward the
intake valve. Lots of opinions on that subject.
Any comments ?
Thanks,
