They're 3/8" coarse bolts so standard torque with your favorite 9/16" wrench should do it. Make sure the thermostat and gasket are seated properly so you don't break of one of the ears from the housing top. Also I hope you didn't opt for the "Safety Stat." I've had several of those fail open when the engine heats a little on a long grade. I no longer use them.
