If you did use thread sealer (and it's a must), then I've had good luck using cheap, aluminum spray paint. Three coats on the gaskets and install them after the third coat is just "tacky".

There is a copper head gasket sealant aerosol product, but understand this product is also a form of glue, so be mindful using this if you plan to remove the heads somewhere down the road.
