Stainless, Bushed PRW Rocker Arms

I am not sure about that hydraulic vs solid, loaded vs unloaded argument. It sounds logical, and i don't have the math skills to prove otherwise, but it would seem a random valve lash number like, .020 plus .004 for (.024) expansion would represent a very small number of degrees of rotation it would be unloaded and getting oil.
I would say on the hydraulic side being always loaded, i could see the lifter plunger acting somewhat like a shock absorber with small deflections or bounce partially unloading it also.
Again, above my paygrade
