5000 rpms for 2 minutes will certainly get the rings to seat. However, they
won't last nearly as long. If you have to put the motor into service quickly
that's the way to do it. It will run well, and if well built, will run well
for quite a while. If you have the time and patience, running it in more
slowly will create a lot less wear and make for a motor that will run really
well for a really long time.

And always follow the advice of the guy that built your motor.
