I still use 30 non-detergent when possible. The detergents reduces friction and the point of break in oil is to allow the components to create a working relationship.
30 minutes of stationary time time varying the rpm constantly, adjusting the tune and checking for leaks. Change that oil to your oil of choice, I'm a fan of VR1 20w50 and then a 1 hrs road trip to maybe a favorite restaurant. Let it cool while you eat, maybe a hour and a half or two, then the trip home. Check for leaks, check the timing, do a valve adjustment and drive it to the next oil change.
Removing the plugs to do the valve adjustment allows you to get a feeling for how your combustion is performing.
