I will let someone else chime in with a specific answer to your question. You will likely get more than one. Lots of folks have their preferred method with hydraulics.

However, for what you are trying to do (just get the engine running decently)….looser is much preferred to too tight. Something more than zero lash, certainly. But what you really need right now is to be sure that all the valves are closing.

Getting everything perfect and quiet can come later.
