I would definitely suggest using a ZDDP additive with the oil. I am only guessing but I doubt if Comp Cams Parkerizes any of its cams. Parkerizing is the final step that some big name cam companies will not even offer, and a crucial step to help break the cam in (a heated acid bath that microscopically etches the metal surface and adds a very thin layer of graphite coating which allows the cam lube to hang onto and penetrate into the cam surface during cam break in

I've seen it for sale at Eastwood's and on E-Bay, haven't seen it in a store. It's just a zinc additive to supplement the newer oils. The Valvoline Racing Oil already has it, as does Brad Penn Racing Oil. I'd go with what Isky recommends, thats what the builder put in mine. These are not normally stocked oils, rated for race use and higher zinc content marked not for street use to comply with the new gov. standards. The zinc plays hell on catalytic converters.
