+1 a lot of folks are claiming .040 but the actual spec is a big .060

.060, only reason to go less is if you run boost or nitrous.

It is not a bad idea to set it alittle narrow when you gap them because they tend to spread out after awhile. Don't set it too narrow or your spark will be small and weak to ignite the charge.
