This will do it. It is simple and fool proof. The process works for all engines with adjustable poppet valves and any number of cylinders. Identifying the valve order is all that is necesary (given in this pprocess for the M).
I do it this way others do a different system. It must be set cold first, so setting it twice (or once) is normal
Set the intake valve on cylinder #1 (Front) when its exhaust valve just starts to open.
Set the exhaust when the intake just closes.
This is the two positions that can be seen on each cylinder to be as far away from a lobe on the cam as possible while still knowing where it is.
The order is (front to back EI-IE-EI-IE)
Look at #1 valves, Turn the engine till the Exhaust just starts to begin opening (moves) then adjust the Intake valve. Rotate more until the intake just stops moving after having been open) and adjust the exhaust. Treat every cylinder (pair of valves shown above the same way, remembering they switch places between cylinders) I put a rag over the ones I have done to keep track of progress, and avoid mixing what I am looking at.

exactly - there are many different ways to do it - but the bottom line is you want to adjust the rocker arm when the lifter is on the "flat spot" of the cam - in other words anywhere but where it's being pushed open, or closing.
Fortunately that's a very wide margine.
Hard to go wrong.
