James I suppose most of the "Engine Break-in Additives" contain Moly. As to the "Assembly lube" I'm not sure. Log onto the products manufacturer's web site, they may provide the information you seek.
In the past I've not had issues with camshaft or engine "break-in" with the absence of Moly in oils or assembly lubes. Although, on my latest FE project and continued recommendation of Comp cams inserted Comp's "Engine Break-in oil additive" into the engine oil. I suppose it's a "mind thing"! After listening to this recommendation over and over, the price of components and the price and labor of rebuilding an engine with camshaft failure, ten bucks seems pretty cheap "mind insurance"! Does it help? Hell, who knows! I believe if a person does the homework, engine woes are few if any!
To make a long story shorter, check for the Moly additive if your looking to protect components from metal to metal contact.
