There is supposed to be a ring-shaped gasket that goes under the thermo, in 
addition to the 'regular' gasket that seals 
the housing.  Don't know if it's actually necessary--diagram shows it with a 
bellows-type type thermo--but it's in the 
parts books.  Moss part# 296-300.   Put some anti-seize on the studs so it's an 
easier job next time.

Don't be surprised if the car doesn't run much hotter.  My BJ8 with a 180deg 
thermo stays below 180 on cold days--50degF 
or so--here in the Bay Area.
