Of course I will mention the obvious - run smaller stem (titanium) valves, with titanium retainers, a rev kit and smaller OD pushrods.
This is the diet package for dependibility and high RPM's.

I respectfully disagree about the pushrods.
I don't care if I give up some weight... big pushrods help more than they could hurt...and the weight of the pushrod isn't really a factor since it isn't controlled by the spring...not directly.
