I=E2=80=99ve often thought, but never spent the time, that there is likely a=
 more modern motor that has valves of similar enough dimensions that we coul=
d use them with some amount of machine work.=20

Has any gone down this path for TR6 or TR4 motors?

Hi,
I've been cruising the web looking at valves for a couple of projects and i=
t looks like the usual sources are listing the fancier 21 4N valves in stan=
dard sizes as unavailable or in less than full set quantities. Can anyone s=

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 exh=
