I have trouble seeing that process as checking v/p clearance. 0 lash, light checking springs, none of this represents the engine in operating conditions. This is more of just a check of "will I crash anything AT o lash, then I definitely won't at normal operating condition for sure". At 0 lash with checking springs you probably have enough clearance if it hits. I am not saying this won't keep you out of trouble. It is very good (generous) at that, but this is not checking actual v/p clearance.
