Stainless, Bushed PRW Rocker Arms

The PRW rockers are more or less a complete roller rocker kit. Mike doesn't do anything to them, he just adds a small correction kit for the geometry on the trick flow heads. So the kit is rockers, spacers and shims to center the rockers and non banana groove shafts.
I did not groove my shafts. It's been 3 or 4 years, not saying not to have that done, or get them.
I only got about 100 miles on mine before I lost a lobe on the cam. After the holidays I will open up the engine again and Inspect the shafts since I will have to get all the metal flake oil out anyways, but i doubt anything will have shown up in that short amount of time.
I like the idea of the grooved shafts, but the images the OP posted of the roller is even more disconcerting
