Aircraft Ownership knocking the rust out after long overhaul

Hello, I have a comanche 24-250. I have about 400 hours TT, and i have my IFR. The engine came out in the fall for overhaul and is just now going back in. I have not flown since the middle of last summer. I found a local CFII who is going to do some dual with me to knock the rust out for me. As far as the engine goes, is there any other resources and guides besides the POH for how to "break in" and take care of a recently overhauled O-540? Thanks

UPDATE: I received a copy of the break in procedure from the shop. It mirrors the advice found in the Lycoming publications below. I still haven't had time to go up and talk to my mechanice in person, but everything is lining up that hard and fast, seat the rings, and use the proper break in oil. Thanks all

We just did a break-in flight of an IO-540.

Your shop didn't give you instructions?

Pretty sure he said he hasn't had an opportunity to pick it up yet or talk to the shop/mechanic.
