The factory rocker arms with the higher spring pressures I understand, but the lifters I don't.
A very good friend of mine was running a custom (BBC) high lift mechanical/solid cam from Crower and never had any issues with his$100 set of lifters breaking. He would easily get 400 passes on them shifting in the mid 7k range.

nothing to do with lift, all has to do with ramp rate. if you have 260@.050 duration on a .750 lift cam that is one thing, now if you have .300 less lift your ramp rate is increased dramatically with the same duration
