No, its the stock covers. I removed the covers one at a time and checked the rods and tightened the rockers back to 22. When I started the truck with either cover off you couldn't hear the knocking. Seems likes its echoing off the covers.

No, I took them off to check the rods.
Fresh oil in there?? Or any oil at all?
Change the oil, my 4.8 has 400K+ on it and right around 4-4500 miles my motor make funky noises. I put in some fresh juice and a new filter and it runs like a top for another 4-4.5K miles with no sounds at all.
