As StephenRC45 pointed out to me a while back, the mating faces on the top of the head (the seats the flanged nuts mate against) cannot be guaranteed to be true, so there's no way to be sure the head sits square. These faces would need to be machined first, then the head set up on the faceplate or jig.

I expect there not to be a lot in it for a one-off head repair, as an NSR head will most likely effectively need to be machined twice. Once to get it to sit square, and then again for the combustion chamber, although I expect it will still be cheaper than buying a new head.

Ideally someone wants to do 10 heads to make the setup worthwhile and bring the price down. If a machine shop were to be up for it (and give a price and service), then while not getting a mass of business, could be recommended as the "preferred supplier" on NSR-WORLD if they wanted. We'd then push any future business their way.

However, as with many things, it's all very easy when you say it fast!
