The factory put millions of thermostat housings on millions of water pumps/intake with nothing more than a paper gasket. Either your housing is junk or the mating surface on the water pump/intake is messed up.




Bullseye...

Got 20+ years on an OEM thermostat housing, over an OEM pump housing, with a paper gasket...

Dry as a bone...



And if you find one that does leak,clean the top of the water pump housing,run the thermostat housing on a belt sander,use a good paper gasket and don't over tighten and it won't leak.I've been doing it that way since I've owned my first car and never used a drop of sealer of any kind.
