Rick, Modern day eg Dole aftermarket good quality thermostats have an enclosed ball bearing in the flat bit that's designed to improve the problem you have i.e. allow a small amount of coolant to circulate back into the radiator when the thermostat is closed. I'm using one in the family car (Toy) and it does work in it very well, it doesn't affect warm-up time in summer but it does in winter ~1 minute longer until the heater fires up with climatic control but I can't see why they wouldn't work just as well in a Datto engine.

I had the same problem in my 1971 510 wagon it wouldn't heat up at all. I used a mates thermometer and I had a total heat in my Radiator was only 45 degrees Celcius even after a huge thrashing. It had me stufffed. I fixed it eventally. I fitted a new aftermarket temp guage and took the thermostat housing of. Which I found the thermostat was a little small and had jammed in the housing sideways. And was letting the coolant jst flow through the engine and radiator. So I fitted the right spec thermostat and it now reached 80 celcius then the thermostat opens. the only thing is when it does my temp gage shows a huge drop in temp as my radiator is new aswell and the temp drops down to like 55 celcius. I have been told this can be a badthinng aswell so I am about to drill a tiny hole in the thermostat so a tiny amount of coolant gets through to the radiator hopefully fixing the huge drop in temp. I hope this helps you.
