depends on the year some adjust and some just torque all the way down... If they do adjust turn the motor one full revolution while watching the rocker arms. each of the rockers will go down then up.when one goes down the other will go up.then when they are both up back the rocker arm adjusting nut off until the pushrod spins . Tighten the nut slightly until the pushrod stops spinning then give the rockerarm nut one full turn.Do this by putting the ratchet handle at the 12:00 position and pull the handle around to the 6:00 position.then turn the ratchet back to the 12:00 position and pull down to the 6:00 position do this and that is one full turn.Then feel the rockerarm to see if it is tight.if it is still loose just give another 1/4 turn...Do this cold...And remove all of the sparkplugs...

How do you adjust Chevrolet valves?
Depending on what motor it is, the most common being the 350, you should want to to start by putting the motor on top dead center, compression stroke. then using the firing order,1-8-4-3-6-5-7-2. Adjust the valves in that order, by turning the crank a quarter of a turn, you will bring each cylinder to tdc individually. Start with number one then move in that order. You want to set the valves at zero lash then give them a third to a half turn further after reaching zero lash.
