When you replaced the head, I assume you got everything back the way it is supposed to be, so I wont waste time going back and rechecking your work. There is a possibility that there has been a sensor failure and/or some component of the wiring harness is pinched or shorted to ground, or there might be an outright failure of the DME. This will be difficult to pinpoint from here so you and I will need to get aligned on what has happened, so far what I have gotten from your story is that your lost power when overheated and you replaced the knock sensors, why? Were they melted? Have your ever done a cylinder head replacement on a M-50 motor before? It is possible the motor is cooked, did you run compression/leak down tests? What were the results? I await your reply.
