as thin of an oil that you can run while still maintaining good oil pressure. once it's good and broke in, a quality synthetic will be just fine.
add zinc too if you wish. how crazy is the cam? my dad has a small block with a pretty mild cam that uses softer spring rates on the valves, and he hasn't given a second thought to adding zinc, and has no problems. I think the zinc really becomes a factor when you get into big cams that need high spring pressures.
