The only thing i can think of, is maybe call up Manley and see what they have in a valve blank. user to cut diameter, seat and keeper groove(s).

MM is right Manley is a good place to start.
Some people don't like Manley any more, but I always had good luck with them.
You might call a Jobber warehouse in your area that supplies machine shops. Maybe you can have them look.
Valve size and stem size are the most important. Too long can always be shortened.
There are folks (companies) that will make you what ever you want, But they can get expensive. I had some made years ago for a Chev 409 ex NASCAR engine I had, no one was making valves for them them. I don't remember the price, just that it was expensive.
The valves could be used from most any Import as long as the specs are rights.
I think Fontainna (sp) or something like thats makes custom titumaiam Valve keepers and caps.. I will see if I can find some more info if you want.

37.5 x 9mm valve options?
I've been talking with rocky jennings who is going to do my big valve heads (thanks papag), but in an effort to keep reliability up, we are thinking the stock 9mm valve stem diameter is the way to go, except neither he nor i know of any sources for that.
Do any of you know where one can get a 37.5 dia. valve w/a 9mm stem?
He also suggested an 11/32 american valve, but then you get into issues of custom valve guides, and the logistic problems he accrues with trying to get enough for only one set of heads, etc.
Thanks for any insight into this,

Thanks for the tips (again), papaG...
I was looking around, and it seems like both opals and some porsches use 9mm valve guides/stems.
This being my first attempt at a higher performance engine, i am most certainly learning way more than i thought i would...
