...yes. If you can find a sealed bearing headset that will work in your application, they are less problematic in this regard. The races for the bearings and the clearances are already set within the sealed cartridge bearings. Unfortunately, they are not always available in the head tube size and stack height you might be dealing with. Be careful with that cutter. It's not hard to remove too much.
