I run BR6EF gapped .032" on motor

on a 200 shot, I personally would run a B9ES gapped .026"

B8EFS gapped at .030 would be the way to go.

Is it his compression, the reason you recommended the 8's over the 9's?

Its really just the 200 shot deal. He's not generating enough heat to need a 9. Our shop car has higher compression than that and is on a bigger hit running an 8 plug. might go a little tighter than .030 on the gap but that's about it.

Right on. I was just curious.

OP, what kind of fuel will you be running on?
