Phil at Fairborn Studebaker sell them.
Not a bad quality, plenty good for all but a very high end engine.

Manley will make up any valve design/size you want for not much more.

FWIW, I have no first hand knowledge, but AFAIK, based on what they've sent me, most of our Stude vendors all buy their valves from the same source. I mean, how many manufacturers are making Stude valves these days?
