I have a 12 volt system, 6.1 Snyder's head, and a Pertronix Flame Thrower 3.0 OHM Coil (40611). Conventional wisdom says with a high compression head that the gap should be .030-.032. However with the Pertronix head the gap can be moved to as much as .040. Experiences? Suggestions? Thank you for any info. Gary D.
