Yes, Go ahead and re-torque the rocker arm pedestal bolts (circled in red) to 20 ft-lbs and the lower injector hold down bolt (circled in blue) to 120 in-lbs.
Then closely inspect the connector that plugs into the valve cover gasket on the inside. If it comes loose enough to look like this
Then the truck won't run right. You can buy retainer clips that slip in there to prevent this from happening, or simply fabricate your own shim to keep it locked in place. Many of us here trim down a quarter to use as a shim

It's just a regular socket. The drops of oil on there make the bolts look different. I don't remember the size off the top of my head. If you have a standard assortment of metric sockets, you'll be fine.

I do. I bought new gaskets and new harnesses at the local IH dealer today. I plan to install them tomorrow. I want to tighten the bolts as you suggested.

Let us know what you find. Most who have done this have found at least a couple of bolts loose. Those who found the bolts loose, were surprised at how much better the engine sounded driving around after being tightened back up.

8mm for the injectors and they get 120 inch pounds.
You'll be very glad you did this.
