valve train forces
What is your reason ?
My ADVICE is the find ways the reduce valve train inertia.
Remember the valve train needs to be accelerated.
A lite valve well reduce required forces, spring pressure requirement and allow the engine to "spin up" faster.
I have seen guys take over a pound and a half out of their valvetrain with springs and locks, no cam change, rev out 400 rpm higher. Motors were quite snappy
