Default Spark plug gap with more power and timing

I am running OEM replacement plugs with about 3K miles on them. I gapped them @ .055", per the recommendation, and they have already spread to about .060". Is this an indication of anything, or is it completely normal?

My mods are below. Obviously, they are producing more power. I also have a 93 octane tune with advanced timing.

Should I still be running a .055 gap, or should I gap them closer or farther?
