Typically, one follows the recommendations of the builder....but feel free to search using the term "break-in". You can use my username to limit the results to the right answer...

There's absolutely nothing wrong with giving the motor some boost......I'd say take it easy for a couple of hundred miles, but seeing 5-7 psi for the first 500 miles won't hurt a thing.
Carsey, whatever happened with that dyno chart?

It also depends on if the engine has new bearings or not. For a fresh rebuild, with new bearings, this is what Ihor and I stipulate to retain the warranty on our ported or stock port motors:
first 500 miles, revs less than 4k, minimal boost
change oil with motor oil
next 1000 miles, revs less than 6k, boost less than approx 0.5 bar (7ish psi)
change oil with synthetic
The reason why we state 'minimal boost' for the first 500 miles is a case of, better safe than sorry. People that don't boost at all for 2000 miles and longer are being overly cautious to the extreme.
