Welcome to the old motor blues.
I have used a thin blade gasket scraper between the housing and head and a hammer to release the thermo housing from the head due to the housing holes of the retaining studs being oxidized, filling the holes.
Just hammer it to release the binding.
Smear anti-seize on the studs for the next time.
Do a new thermostat while the housing is off
The screws holding the thermostat housing top will likely be corroded and break off.
