If the camshaft is the "brain" of precisely timing your engine's 4 stroke events, then consider the rocker arm the "muscle". Communicating the desired camshaft spec features to the respective valves is accomplished by the LS valvetrain components (lifter, pushrod, rocker arm and spring). Each part plays a role in the timing of when the valve opens and closes, but the rocker arm place the lead role due to the fact that its fulcurm properties allow a multiplication of the camshaft's lift.
