I'm calling this one fixed but will continue to monitor closely. Pics of the surgery:
Disassembled the 5800 brake caliper and filed down the part of the caliper interfering with the headset
Quick touch up with a paint pen
Able to mount with no interference!

I now answer to gugie, Crapmaster, and Nostradamos.
