It might be your valve lash caps that are getting loose as I don't believe 4.7's have lifters.
Well, I didn't see any when I replaced my cams on my old 4.7L.
Try to grab a set of H.O. camshafts if you do rebuild if they are still available. I got them for about $60.00 from the dealer back in the day and it was good for about 15hp and 25lbft.
