Re: maximum wear for 356 valve stems?

Kanter, Max, etc. all would have them. Whether they all come from the same source I don't know. I've usually bought mine from Egge, ditto for the valves, but the last set I believe was bought from Kanter for a 1938 Eight (120) and the fit just fine. Still, if I'm also buying valves I'd be more comfortable buying both guides and valves from the same source. Try Egge first. And sure, use the newly installed guide to face off the seats.

Does your friend have a power valve seat grinder? Not that it will necessarily be needed - depends on the condition of the seats.

A simple old-time method for final checking before installing the springs etc. was to use a soft pencil and make a series of radial lines across the valve face and then rotate the valve by hand, checking to see that all lines were equally broken and that the contact face width was reasonable (within specs). If the contact face is too narrow it should be widened (few more seconds with the seat facing stone). If it's too wide, the seat needs to be narrowed using stones of different angles. Probably could do just as well with Prussian Blue as with a soft pencil, but doing this gives great peace of mine before staring to reassemble.
