What's the proper procedure since putting 1000 miles on it under 4k RPM is not realistic?

New rotor bearings, among many other internal parts, not to mention a new ECU with only a base map.

Do I start it, run for 30 mins at low idle, change oil, idle under 4k RPM all day outside the shop and change the oil every few hours? 10w-40 for break in and then go to 20w-50? Rent the dyno for a day and run it under low RPM load?
