Any tips for removing a housing that has been in place for many (25+)

Can you get the bolts out or is that the problem?

I seem to remember that often the bolts came out OK but the housing
tended to be rather well glued in place by the gasket cement.

Do you need to preserve the thermostat housing? If not then just
break it,

Oh, you will break it, trying to get it off. They're made of cast
easilybrokium.

is that similar to "muckite"?

Yep. Mezac or 'pot metal'

Copper zinc alloy IIRC
