We run .035. on AR plugs
More does not seen to help and just puts more strain on the the rest of ignition system in my opinion.

I have that box on a 302 Ford. At .050 it was hard to start. Improved a lot at .035. Autolite plugs, too.

.015" difference in spark gap makes a negligible difference in spark output as observed on an Oscilloscope.
