Spark Plug gap?

[PerBerglund]

In my 410W with about 10.4:1 comp I figure I try a little warmer NGK FR4
An MSD6AL + Blaster 2 is feeding
Looking around what spark plug gap would be recommended but varies from 0.035 to 0.06

Any recommendations?

.035" Is my choice.

But Everyone has their favorite #.

So chime in, My fellow gear-heads.........

Yes 0.035 seams to be popular and I have run 0.045 without problems so I guess it is a matter of "trial & error"
Less cap I guess will keep the coil happy for a longer period

I ran .045 with my Mallory VI and compatible HEI coil, but back down to .035 with the ProFlo 4 system. FWIW when I was on the juice, the cold plugs were gapped at .025.

Thanks for the input!
