Also even with the springs/retainers... balance of components because a VERY important issue... I wouldn't want to rev my D past 7.5-8k. without a full balance/blueprint of the bottom end...

Over-reving an engine isn't a good idea... unless you've takin a LOT of things into consideration.

Quite right - but it would be a good idea to allow your motor to go into higher rpms to take advantage of the power a hiperf. cam can create - but like you said, its a bad idea to say, rev your stock motor to 9k when it redlines at 8 - obviously.
