He's going to start with the head that came off the engine that's currently in the truck. If that head isn't viable, he'll move on to the derelict engine's head. Both head are the 848 variant, but the first head is a couple of years newer than the derelict head. Newer one has a pipe plug on the outside and the other one has on oil line. If i end up with that head, I'll plumb the oil line in and use it.
