I have a fuel problem

[jorgeinmiami]

I bought the 2 new thermostat housings and installed them yesterday.
Found it odd that it shows that there are no gaskets that go in-between the housing's and the head, but placed the thermostat's in position and tightened the bolts and placed the hoses in position with new clamps. Cranked the engine and it still leaked from both sides where the housing meets the head. Tightened them a little bit more but still would leak.


I looked at a parts schematic and it does not show any type of gasket either

My next idea is too either use some type of form a gasket or make a gasket out of material ?

Or is there something I'm not seeing??????
