Lightened Rocker Arms
Lightweight and friction free valve trains are a good thing for happy
performance motors.
Bee-hive springs, lightened rocker arms, titanium locking nuts and 5mm
valve kits are a great idea for higher revving and also when sensible
spring pressures are used.
Note: Extreme spring pressures are horsepower
robbery.

Tech tip: Lighter valve trains can be super beneficial for performance increases when "combined" with 5mm valve kits, bee-hive springs, titanium jam nuts and lightened rocker arms. The above photo shows the excess material that can be removed to get the full benefits of lighter weight valve trains. Lightening the rocker arms near the pivot shaft would be a waste of time. Your goal is to lighten as far out as possible.
