Use sealer on the 4 corner intake bolts (where the water is) and it wouldn't hurt on the others, although not necessary.
Moly lube is good for the top head bolts, but use good sealer on the bottom ones. Not familiar with your head gaskets, but like USMC said, that's a big no-no in my book. Unless the manufacturer says you can, and explains how. That's the ONLY way head gaskets would go back on.
