Anyway to answer your question you can either adjust ride height via the pushrods instead of the turning the collar as mentioned above. And you can play around with adding or removing shims at the rocker arm (same effect as moving the shocks at tue shock tower).
For the rocker arms i think the plastic ones work just fine. Just install bearings instead of using the brass bushings for smoother operation.
