I did the mod, and I still tossed a guide, so I see this as a pointless mod... If you are throwing shims, something isn't right in your head..

I upgraded to jwt s4 cams, and I went back to stock springs and retainers. I had BC springs and if your springs are too stiff for hydraulic lifters it could be counter productive. Also all guides are the same size so it's hard to get the rocker "level" with the cams.. I went back to the standard guide/shim.

If there is enough movement in the rocker arm, you will still break the walls in the guides.. IMO this conversion isn't worth it.
