Any sealant/RTV with gaskets?

Gentlemen,
I'm putting my 292 back together and was just curious if you use any kind of sealant or RTV when installing new gaskets? At this point, I'm particularly interested in the valley cover, timing cover, water pump, and head gaskets, but any other pearls of wisdom are always appreciated.
The gaskets are Fel-pro from a kit from Rock Auto and are felt(?) style gaskets, not metal.
By the way, the gasket kit seemed really reasonable, too. Right at 90 bucks, shipped, for every gasket and seal I think you could need on the engine, and several doubles. Thanks.

No sealant should be used on the composite head gaskets, or exhaust manifold, exhaust outlet. I have been using a light application of grease on both sides of the intake manifold gaskets with no leaks, and it makes their removal and reuse easy at a later date. Seal the valve cover gaskets on one side to the valve covers with them off engine and let setup overnight. Then the covers and gaskets can be removed and reused. Nonhardening aviation sealer to the oil pump gasket, and I use it on the thermostat housing gasket. RTV to everything else, judiciously.

On the exhaust manifold and exhaust outlet gaskets, antiseize compound applied to the surfaces can allow reuse of the gaskets, and makes cleaning surfaces easy later on if they need to be removed.
