7.3 Head Gasket
Just got done replacing a few injectors, got my truck running good. Felt good enough I put about 1500 pounds of square bales on the bed and I had made it about 15 miles and noticed the engine starting to overheat, luckily I was pretty close to my destination and limped it there. Got done unloading the hay and by then the truck had cooled off so I opened coolant cap because it had already sprayed everywhere out of the cap I assume. I started the truck up and coolant immediately began boiling out of cap non-stop. Looked in my oil sump and it looks like a milkshake in there. I am assuming my head is blown but have no clue how I would have blown the head going 60-65 down the highway with hardly any weight on the truck. Truck is blue/white smoking heavily and idles okay.

Welcome to FTE. 
There’s not many head gasket failures on the 7.3L. I think I would investigate a bit more, look at oil cooler etc, BEFORE jumping to the conclusion of a head gasket. When you inspected cups did you pressure test them or just visually look at them?
