Yeah, should be good.

Experimented a bit and found out that with the following sequence you do a cold start up with valves open

1. Press start without foot on brake
2. Select Sport Plus
3. Press accelerator (engine still off)
4. Then turn engine on
5. Start up with valves open

So yeah, based on this, valves should be fine at least on start up I guess.
