Tim, all I know is, and its very little, is I paid $800 about 10 years ago to have my 216 re-babbited. I would feel better about that price had Jerry (in another thread) not burst my bubble and corrected my assumption that all the bearings were re-babbited. Had I understood more about the engine, I would have purchased the vendors insert kit and been done with it. After that pain, I started rebuilding 235's again. So rebuilding a 216 wouldn't be any more work than a 235. Amazing what you learn when you aren't paying attention. LOL!
