By rocking, I believe they mean that the rocker is actively pressing down on one of the ends of the valves that is being opened. If this is true, it means that you wouldn't be able to rock it back and forth between the end of the valve and the end of the pushrod with your fingers.
Though the experts may say this procedure is a better way, I find the TDC method of adjusting intake and exhaust for the same cyllinder a much easier and foolproof method for the hobbyist like myself. The only kicker here is adding the second mark on the flywheel, which is a piece of cake if the engine is out of the car. Steve

Question regarding the valve adjustment approach outlined in the classic threads. In the table below, when it states "Turn until Rocking", does that mean when the rocker is pushing down on the valve? I originally thought it meant when the rocker "rocks" on the rocker arm (by hand) which had me very confused (not hard to do?).
Clarification is appreciated!
