It ran until that point. Why don't you just put a gasket in it and drive it? If the head is not warped and the gasket will seal then you should be OK with just putting a gasket in.
Yes, there might be damage to the cylinder but is it that bad that it would not run again? I would not do a half rebuilt. That is money wasted. Either refurbish the whole truck, or send the minimum to get it operational again. Keep your eyes open for a 97 that is in good shape. When you get the new truck, transfer what you can and sell the 93.
The labor to swap a used engine is normally not worth the effort. You end up doing so many "while I am in there" things that you overspend. It would only make sense if you can locate a 50k mile engine. Anything over a 100, you might as well do the headgasket while out of the truck. Then you open the motor and find some stuff you don't like. Old truck, not worth much expect to you, you will be upside down in the truck before you know it. Take the emotions out of it and look at the condition of the rest of the truck.
