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 also filed down my 5800 front brake caliper to help clear the headset. I didn't file mine down quite as much as yours, but I still need to use three washers behind the caliper. The offending portion of the brake caliper seems really beefy, so we should be fine right?? I sure hope so...I've got about 200 miles post-filing with no issues.
