[Healeys] Thermostat gasket sealant

[sbyers at ec.rr.com]

Since I tried Hylomar, it is all that I use on gaskets (Permatex has an equivalent).  It seals well and is non-setting.
For thermostats, I tried the sleeved 160 that Moss offered (apparently no one had a sleeved 180) in my BJ8 and found that in the wintertime I had to actually block half of the radiator to get the coolant to come up to temperature.  Later, I was fortunate to be able to score an original NOS sleeved 180 made by AC from Kees Oudersluijs who was active on this list and got a couple of spares as insurance.  
A thermostat doesn’t really “control” the coolant temperature, but reacts to it depending on the coolant flow and temperature of the air through the radiator.   Initially, it limits the flow for faster warm-up of the engine.  Once it is wide open, it is out of the loop.

My 100 will not come up to temperature (at least yet) with a 160 thermostat.  I am putting in a 180 and wonder what is the preferred gasket dressing?
