The fact that "pointing down" is an imprecise designation is exactly why you look at the overlapped rockers on the companion cylinder instead of the downward-pointing cam lobes. 012 step, then the clearance is within spec. First, when I started building engines with hydraulic lifters I tried these "procedures" of soaking and pumping, pumping and soaking, etc.
The point in the valve-operating sequence to check a pair of valves is when another pair is 'rocking' - the brief moment when the rockers are moving in opposite directions to close the exhaust and open the inlet valve. The cam lobes lift up one end of the rocker arms, which forces the other ends down onto the tops of the valve stems, opening the valves. To assure that the valves for a given cylinder are closed, rotate the engine so the piston in that cylinder is at top dead center, which is, by definition, the position at which the piston is at the top of its compression stroke. This is sometimes called the overlapped position. You can block the wheels, put the car in neutral, put a socket and wrench on the crankshaft nut, and turn it.
