RE: ISX head identification
The part number and s/n are stamped into the drivers (LH) rear side of the head.
Genuine Cummins Reman will have RX following the Part Number!
New will ONLY have the Part Number, no letters following.
Aftermarket machine shop WILL NOT/MAY NOT mark the head, but if it's been used it should have some form of telltale signs. Aftermarket machine shops who do good work and are proud of it, usually have their own markings they will stamp onto the head.
