Not sure what problems anyone else has had, but the one time I was running a
Tstat, I had head gasket leaking coolant into the lifter valley. Since then I
have also added copper wire to the head gasket between the coolant passages and
the lifter valley and no more TStat. Last year I started running a restricted
line from the heater valve connection to the tstat housing to allow a little
more flow at #4 and to serve as a steam vent. Joe(B)

Inquiring minds want to know... Why Bob?

The wet liner engine is far from rocket science. Getting the figure 8
gaskets and liner protrusion right is the only tricky part.

I did that too. A bigger radiator makes a big difference. On a TR4 it is
pretty cheap and easy.
But without addressing the lousy coolant circulation you are still going
get localized overheating. Combine that with really low block pressure and
you get the classic #4 overheat.
