If you Google for "aircraft cylinder break-in" you'll get about 488,000 hits. Each manufacturer (Continental & Lycoming) has a Service Bulletin about it, most PMA cylinder makers (ECi, Superior) have a procedure, and many of the custom overhaul chops (Pann Yann, Victor, RAM) have one. Some of the type clubs have one - even Shell Oil offers advice. That's a lot of reading - it's probably smarter to just read watch Mike Busch's webinar.
