I recently bought a 318is as a shell, but the engine and everything is still in it. The main bearings are rattling around in there when it turns over so I assume the head is just fine. It seemed to be good when it cranked over. I was gonna just swap the main bearings and run it until it quite then swap it but I found a cheap m42 with less miles that I am going to use.
Anyway, odometer stopped in 08 at 145k. I had some records from a shop that showed it getting routine maintenance in 2010 so I would assume that it has somewhere around 200k on it.
Make me an offer on any parts you would be interested in from the motor.
