Thanks.  It is different than the TR3 and uses a 45 degree elbow one piece
fitting.  I'll look tomorrow and see if there is clearance without the nut. I
think the stud is also in contact.  If not, then it is time for a little pipe
fitting as mentioned as removing the head seems a bit much for the sake of
pure originality.  Thanks, jim henningsen

Must be some mistake.  The TR4 uses a cable-operated heater valve, that sits
on top of a 45 degree street ell that screws into the head.  Totally different
setup than the TR3 with the handwheel and extension tube.

I'm not positive, but I think that if you remove the head nut & rocker cover,
there will be enough room to install the elbow.  If that doesn't work, then
your only alternatives are to remove the head; or use a plumbing nipple and
regular (female-to-female) elbow.  Removing just the one nut should be safe;
as long as you reinstall and torque to 102 ftlb before trying to start the
engine.
