Michael,
Roller lifters are very prevalent in FE's. I would venture to say that the majority of Keith Craft's street motors are hydraulic rollers and his race motors are solid rollers.
I think that 6000 rpm is a good cap for hydraulic roller camshafts, but most street motors that are meant to have torque and low/mid range manners don't need to be revving any higher anyway.
