Blown 440 spark plug gap

Hey yall,

I’m trying to figure out what I should gap the spark plugs on my 440 (ported iron heads, forged pistons, 8-71 BDS blower running 15psi of boost)

I haven’t raced it yet and have only cruised it around at a few fairgrounds/cruise week events and I previously had the plugs set at .035 but I’ve had some problems with it popping at low throttle and when starting up. I’ve heard 2 different camps saying open it up or close it up.

What are y’all’s recommendations?
