Works different on different engines. Valve lash is what determines valve timing - that is the reason for proper adjustment going by the generalized factory setting that works "good enough" for all.

I've double-checked that procedure against the factory procedure,and so far - it has always worked. That is, excpept for engines with cam-operated compression releases.
