Question
Looking for a source of Sodium filled valves with a stem size of .4685. Most I have found are in the .547+ range. Also looking for valve guide seals for same.
Any ideas?
Hey Doug:
Wow , that's a 12 mm valve stem ! Don't drop one on your toe !!
I would start looking with Goodson Machine Shop Supply (www.goodson.com) then try Ferrea Racing Valves. (www.ferrea.com ) Of course there are a few others, but they are two of the biggest that I know of. They are both honorable companies that I have used in the past with consistent success.
In the case of Ferrea, I know that they will make custom orders, but you should have your wallet real ready for a shock.
If you don't have any luck, write back in a day or two and I'll put it to a pro engine builder nearby. He has a goldmine of sources that I don't know about .
Good luck
