That will certainly work, but it's complicated and a PITA. That's the way I do it on the stand when building a new engine before it fires.
I always adjust while the engine is idling once the engine is up and running. These are hydraulic lifters right? It's best to cut the top out of an old valve cover and install it finger tight to avoid loosing oil all over the side of the engine.
With the engine warmed up and idling just loosen each poly lock and back the adjustment off untill it starts to click. Then slowly tighten it back down untill the click just stops. Then give it about 1/2 of a turn and lock the poly lock. Move on down the line untill they are all done and then do the other side.
