Yes you need a gasket between the thermostat housing and the engine. Usually a fiber type, should come with the gasket.
In a perfect machine, the metal to metal contact would be so exact that there would be no leak even under pressure. This is not the case on most cars. The gasket allows for slight imperfections in this contact area. Even better is a gasket with a little automotive silicone material allowing for a good seal under heat and pressure.
