Detroit diesel engine 8.2 L

I have a 8.2-liter V-8 diesel engine known as the "fuel click."
I am repairing it and I do not have the repair manual. I need the calibration of the injectors and valves, as well as the tightening values ​​of the cylinder (butt) covers.
I appreciate that someone sends me this data if you have them. It can be A:
If someone can tell me if there is the repair manual in some place where you can download, I appreciate it infinitely.
A cordial greeting.
