Many times, when a reman head is purchased through Cummins, the reman head will be a new one in the crate. Hopefully they did install a new head, and not just slap your old one back on, many shops do that and charge you for a new head.

If they installed an aftermarket Chinesium head, be ready to install a new one. Hopefully your shop bought through Cummins, because odds are, that reman head was a new one, and hopefully you dodged a bullet.

The way to tell is to look on the back of the head for the serial number, it will be welded into the metal. If you have one of those bore hole inspection cameras, you may be able to snake the lens around to read that serial number to determine new or reman.
