I ran into this post on bobistheoilguy. It's a lengthy article with much info about the 4.8, 5.3 and 6.0's.

 

Thought I'd share.

Quite a good read; saved a copy. My son is lucky enough to have the cast iron block in his '07 2WD 'Hoe, so hopefully we won't need this. But it's here if we do, and thanks for posting it.
