I wouldnt worry to much about over reving these engines when they are new and pussying about, drive them like you intend to drive it (but not to the limiter) but with three rules:
Absolutely not until it is well and truly warm,
Always vary the engine revs, so it beds in evenly at all speeds (sitting at one speed on the motorway for a few hundred miles is bad, bearing shells dont wear properly like that, got to vary it all acroos the rev range)
Never let it labour
And if you can help it, avoid really short journeys when its cold, sh*ts the oil up quicker. And if you can, get the oil and filter done after 1500 miles, by this time any bits and high spots from the bores will be in the sump or the filter, and you want them out of there. If you go to the dealer, insist on seeing the old sump washer and filter, some of the b******s use an extractor and suck it out the oil filler cap, leaving all the sh*t in sump, and some may even charge you for it and not actually do it...........
