For the spark plugs, is it possible the center electrode broke inside the insulators and dropped down to close the gap? Crazier things have happened.

Yes, the bearings were part of the kit I purchased from Butler. I will try to speak with them Monday, but I'm waiting on more info from the machinist. He's going to do some measurements with different bearings, stock crank, etc..
In my opinion, they should sell the kit with a narrow bearing or reduced radius (fillet). The customer should have no need to machine the crank for this. At the least, send a note with the kit that this needs to be checked.
Also, I wouldn't be surprised if this is either a manufacturing defect by Scat or Clevite. I doubt Butler would even check something like this on their own builds,
This cannot be a normal thing, otherwise garage hobbyists are doomed. If a hobbyist needs to go to this level of inspection detail on semi-finished parts, it becomes an unworkable project for most of us.
Moving forward, I would caution anyone against purchasing their own parts and doing this. Let your machinist prepping your block purchase the parts and have responsibility for them.
