I had a bit of a problem with a cork gasket. For some reason, either the
sealant I used (Hylomar) or some paint left on the block interacted with
the cork gasket. It literally melted away! The cork gaskets also have a
tendency to squeeze out of the gap if you tighten them too much, which is
easy to do.
I found also that my thermostat housing was so corroded that there wasn't
a whole lot of sealing surface left. I flattened out and cleaned up the
sealing surface by rubbing it on a large knife sharpening stone. I then
sealed the studs per Barney's suggestion. For a gasket, I made my own
out of a thick paper gasket material that I bought at my local parts
store. The material is made specifically for water pumps and other
cooling system parts. No leaks so far!
A big sharpening stone is a great thing to have around for cleaning up
and "truing" gasket surfaces. Make sure it is as flat as you can find,
because not all of them are.
