Small block heads with Z casting - 10/03/09 11:30 PM

A Friend of mine just got a bunch of parts with a car that he just bought. In with everything is a set of small block heads with a "Z" cast instead of the "J" or "X". Does anyone know what these are?
thanks all

Most likely a 915 casting. In 70 and I think 71 there were J, O, and Z cast into the 915 heads. Ask him to send the casting # off the runner.
