Seems a bit ironic, the most violent and delicate R&R projects are side-by-side, literally, on the steering head tube.
Removing the original drive screws, without damaging the VIN tag, takes sound judgment and a surgeon's touch. Being able to remove them, intact, such that they can be reinstalled is rare. They're usually oxidized in place and the original friction-fit was, by design, extremely snug. 95+% of the time, it's best to just centerpunch then drill the heads. And that's not easy to execute well...but...it can be done.
As for the steering head outer bearing races, those don't necessarily have to be removed. They can be masked. If you're going to remove them, best to do so after the paint is applied; that way the seats will be clean, bare, steel. The interference fit is so tight that a minuscule coating (like overspray) will create a nightmare, come reassembly time. A feeler gauge, or fingernail, can be used to verify that these have been fully seated. That is, if you lack experience, or a dental mirror.
Refinishing one of these framesets, doing it right, is a painstaking process. Like anything else, it's all in the details. Unlike the autobody equivalent though, it's mostly details and what might be passable on a body panel will look horrible on a bike. With K0s, especially, look closely for small stress cracks along the outside edges of the triangle, above the upper motor mounts; if found, they should be welded. Most of these framesets will have some rust pitting and at least a few small dents, most of which won't be visible until they have been primed & blocksanded...then viewed in optimal lighting; that's what'll bite your arse, if overlooked. There's nothing like a fresh application of candy color paint to magnify surface imperfections. The factory didn't always get them 100% right either. Don't be surprised to discover a few paint runs and some leftover welding slag, as you carefully blast down to clean, white, metal. The question becomes what are you willing to live with? Translation - lots of skilled labor and patience and the latter can go a long way toward overcoming a lack of the former.
