You may prefer to adjust the valves as you go, or measure them all before returning to adjust those valves that require adjustment. If a valve requires adjustment, make sure the camshaft sprockets are in the proper position before attempting to depress the valve or remove a shim. This will prevent any unintentional valve interference problems.
