"Where the head and housing meet it is not flush, small imperfections."

Brenda,

My '41 120(similar setup) had that problem, also the housing face wasn't flat. So I filed the surfaces on the head and on the thermostat housing to remove as much of the imperfections as possible, as well as flatten the surface. Initially I made a thick cork gasket but more recently used a good quality paper gasket. Also used Loctite non hardening gasket cement with a coat brushed onto the head, a coat on both sides of the gasket(messy) and a coat on the housing face. Also tightened everything down at once, no 24 hour wait, and wiped off any excess gasket cement that squeezed out. Worked for me.
