It depends if it is an OHV(pushrod motor) or a s.o.h.c./d.o.h.c. motor. Ohv engines can have a timing chain set that allow for adjustment, to be installed. You can also install crank keyways that adjust the timing by moving the crank cam gear the required degree/s. Overhead cam engines can have cam gears installed that allow for cam adjustments.

variable valve timing is where the engine changes valve timing based on the driving situation much like ignition timing is changed to meet the needs of the engine in specific situations. in most cars valve timing is static and determined by the timing gear on the camshaft

This component is electrically operated by the engine computer. It (on most vehicles) changes the oil pressure in the variable valve timing system to adjust the valve timing. It is very similar to the solenoids in use inside an automatic transmission.

Only some aftermarket shocks have an adjustable valve. You most likely don't have an adjustment valve. List symptoms that make you believe you need better shock absorber performance.
