Water pump gasket alone or with sealant?

You dont need to use any type of gasket sealer. But I always do. I usually apply something like Permatex Hi-Tac to water gaskets. Just to fill the little imperfections in the metal.

Thanks Dave. Don't want to have to do it twice. Anyone who runs 11.80's, can give me advice anytime! : )

Do you have a Cleveland? If so, get a REAL Cleveland thermostat. Do your research because the clever "associates" at most national parts houses will hand you a Windsor thermostat. "Hey, it's a Ford 351, right...same thing." No, Cubby, NOT the same thing!
Lots of Panteras have the thermostat removed for "constant flow". Bad idea because of the way a Cleveland bypasses. You're way better off with the proper thermostat than with no thermostat at all.
I have a thermostat kit sold by Dennis Quella at Pantera Performance. Now I can't remember if it required removing a restrictor plate...adding a restrictor plate...or both, but I do remember it was a pain in the ass with the engine in the car. If your engine is hopped up, you may want to call him and ask about this kit. If your engine is mostly stock, a stock thermostat will work fine.
Later, Mooso.
