 As an alternative, here's one supplier of custom valves.

 I’ve often thought, but never spent the time, that there is likely a more modern motor that has valves of similar enough dimensions that we could use them with some amount of machine work. 
Has any gone down this path for TR6 or TR4 motors?

Been back ordered for nearly a year now.  Seems TR4 exhaust and TR6 intakes are scarce.

Hi,
I've been cruising the web looking at valves for a couple of projects and it looks like the usual sources are listing the fancier 21 4N valves in standard sizes as unavailable or in less than full set quantities. Can anyone shed light on this issue?
As-of right now, I'm SOL on one project because of this.
I'm not looking at big valves... just stock-size (1.43 intakes and 1.28 exhausts, but the forged 21 4N jobs that come with the back side cut - sometimes referred to as "gas flowed".
Regards,Bob Lang
