No argument - just a question.

Note: I use the recommended method of adjusting: Intake almost closed, adjust exhaust; exhaust just opening, adjust intake. I tighten the poly-locks until there is no slack, then a half turn.
It does not make a difference.
If I have already installed the cam and lifters my next step will be to figure out what length push-rods I am going to run.
I will "mock-up" a length checking push rod and roll the engine over and check my "pattern" on the valve stem if all looks good then I will measure the length of the push rod checking tool and find the right length push rods and install them.
Then I will adjust the rocker arms one at a time in the same way you described above.
For stock rebuilds I will use 1/2 to 3/4 pre-load.
If I know he will be racing of thinks the engine will see over 5,000 rpms I then will only run a 1/4 pre-load.
When I build an engine the very last thing I do is fill the engine with oil to "prime it".
So to answer your question it does not make a difference that is the last thing I do to an engine before I ship it or the customer takes it home.
