Spark plug gap

Hey Mom, for what it's worth I run the MSD 6 Al. It is an older unit, maybe 10 years old. I have a basic Mopar distributor. My coil is from Pertronix. This coil is supposed to put out 60,000 volts. I have seen this thing make sparks. Mom, this coil makes freeking lightning. My gaps are set at .045
