Ive been researching this too and it seems to be a personell preference.some tell me inserts others say rebabit.I posted the question on jim carters ask jim knowing that both options were avalable from carter.His sugjestion was to go with the inserts.Ive put my 216 rebuild on hold untill im sure whitch route to go.As for the oil question in an old and dirty engine use nondetergent to keep the crud where it is.In a clean or rebuilt engine you can use a detergent oil.
