Rocker shafts are usually reused. One side often loos more scuffed than the other, but you can install them so the scuffed side is away from the cam (where it won't be under the same pressure) you can spread out the wear.

If you can feel a ridge between the wear area and the outsides which don't get worn, then it is time to consider replacing them.

Guiding all those cam bearings through all those journals is tricky. But you have plenty of time to practice with the cam out and the cam carrier out. It is a bit hard to visualize how a lip could form on the flywheel side of any of the journals. Equally hard to think of what would allow journals through a bearing area one way, but not the other (unless it was that you could get more brute force on it in the one direction.

How come you couldn't try to tap it out the regular way, once the cap was off?

Tightening the head studs on reassembly is always one of those worry points. I have the cam in for this, and keep turning it as I go through the head stud pattern. As long as it will turn freely (or as freely as the thickish Torco assembly lube will allow) when you have tightened the final bolt, all is well. You might not think that sturdy cam carrier can bend, but it can flex, and a little is all it takes. So far, loosening the head nuts and retorquing has always done the trick to free things up.
