Don't use any gasket sealer. As knowels said, the factory gasket has a section that compresss and provides a perfect seal, If you goober sealant on the gasket, it can squeeze out and clog the very tiny coolant passages and lead to a cracked head.

As far as the clamps go, I'm sure the spring clamps will be fine, but they are a pain to deal with, I relpaced mine with worm gear clamps.
