LS rocker needle bearings on top of head

[LH Lead-Foot]

With one rocker arm cover or valve cover removed, I found two needles bearings that came from one of the rocker arms. I was starting to reseal the engine with a complete engine gasket set. Glad I was doing this now anyhow.
I have looked into it and see a lot of kits from imported kits running from $55 to domestic kits at $150 & up. They indicate the use of captured needle bearings cups that are pressed in the rocker arm. Now these kits come with little tools, like large hole washers to push the OEM rocker arms needle seat out of the old rocker, clean up and press in the new ones. Plus, a few, sell brass bushings that eliminate the needles completely. Other sell rocker arms updated complete and ready to go.
Question; Has anyone had this failure or have experience with the different kits offered?
