Yep, sounds like it. There's a procedure to do them with the engine not running. I usually prefer to do them with the engine running.

What was the reason for the adjustment? Normally, once you adjust them they should stay in place unless the rocker nuts get loose. If they were making clicking noises, you probably should replace them. If you tightened them to get rid of the clicking, you probably bottomed them out --not good.
