x2 BBCMudbogger, all this baby-it advice is pure BS. You have to LOAD the rings to seat them, drive it around the lot and GET ON IT full throttle up to 3/4+ of your redline RPM. You run the risk of poor ring seal if you don't.
Also, there is NO break-in to bearings, they are good or they are trash, babying it won't help or save it if there is a clearance problem that wasn't caught during assembly.
