Spark Plug Gap

Today I took the time to set my spark plug gap to .040. After some research it seemed to be a consensus for those running the Pertronix Ignitor and Flamethrower. I was extremely surprised to find that the spark plugs (Champion H10s) were not even close to uniform in their default gap. According to my gap tool, they ranged from .025 to .040 right out of the box. I set them all to .040, put them back in, started the car, and it runs. I am not sure if I will notice a difference, but I am sure every little bit helps.
