3. There is an oil analysis thread somewhere floating around the forums that breaks down the amount of zinc in each oil that was tested. You may have better luck looking in the oil/maintenance section.

4. You can purchase zinc additive that is separate from the oil it self, or you can purchase oil that already has the zinc added to it. Just depends on your preference.

Thanks for the reply. Seems like I opened up a whole can of worm since I decided to do this cam swap...as in there is a lot i need to learn/read up on. So far Amsoil Signature Series seems to be a pretty good product.
