I got them, but with mods, I may need to adjust that number down.

.60" is factory gap. When you go colder, the spark isn't as strong (hot) and the gap needs closing. Running a .52-.55" on 104s and 103s is an accepted rule of thumb.

I'm running a .050" gap with my AL103's. Runs pretty well, but I agree with Rook. For your purposes I would go with .052", since the GTP stock gap is .055"
