don't all speak at once
so i asked a friend at a machine shop. here's what he said. feel free to chime in if you disagree:
valve locks: who cares
balls on the rocker arms: woulda been nice, but prolly won't matter
valves in the right hole: yes, matters only as far as the seats go, not the guides. if putting back together without lapping the valves then it will matter alot. if you are lapping the seats and valves then it won't matter.
