Without having first looked at the link that Josh has posted (I will do that after I put my foot in my mouth).
Here's how I see it;
1)bearings need no more than a few kms.
2)Rings need load and they take quite a few kms to run in.
3)Cams if you are running new cams and/or you have changed the followers, then they need to be fluctuated for 20min at between 2000 and 3000rpm from the minute that the engine is started and not allowed to idle.
4)I feel that gaskets (head gasket) need some warming and cooling to set them - after re-torquing then it is all O.K.
I like to run an engine for about 20 mins loading it up by varying throttle. Before taking excursions towards the upper RPM (6000). After I have driven the engine for a couple of hundred KM (when I am feeling patient), an oil change, re-torque head, boost it and then drive it like it is stolen.
