I've had the best luck on my thermostat housing using the following procedure:

1. Cork gasket (either get from one of the vendors or cut your own, cork gasket material is available at most autoparts stores by the roll).
2. Attach gasket to thermostat housing using a thin coat of permatex no. 2/indian head shellac/RTV - your choice, I prefer the indian head shellace.
3. Put a thin layer of grease on the gasket on the side the faces the head - this allows you to remove and re-install without having to replace the gasket every time. I use the same procedure on my oil pan, and I've had that off a few times with no damage to the gasket.

Good luck!
