Check Wayne's rebuild book. In the back is a good procedure for breaking it in.

In general, I would say to "set" the moving parts with conservative RPM's for 50 miles or so, and then change the oil to the good stuff. Once that's done, warm it up and let her rip! With a properly lubricated motor, there is very little metal contact, as you well know from your teardown. Once rings have seated and seals are all snuggled in, she should be ready to run, and as we know, oil pressure rises with RPM, and higher pressure keeps the film of protection in place. It is the low pressure of idling in traffic that kills these motors.
