Re: Engine noise, maybe a lifter????
those symptoms are textbook of primary timing chain tensioner/guide wear. but that problem was fixed a few years before your truck was built, so I'm not positive.
as for the start up rattle, that may be the hydraulic tensioners for the cam chains, one in front for the left bank, and one in the rear for the right bank. they screw in to the cylinder head externally with a 27mm socket. they have an internal spring and are also fed by oil pressure. over time the spring wears out, allowing them to give the cam chains more slack until oil pressure can rebuild in the top end to assist the springs in providing tension to the chains. the noise you are hearing are the chains slapping the loose guides before they provide this tension.
this is as per Ford repair bulletin #00M12 i believe
