My guess is you will find mouse pee and poop corrosion all the way to the oil pan down the oil drain holes and push rods. The rockers will all be frozen to the shaft, the bolts, push rods, valve springs, keepers and valves will all be corroded beyond use. The valves will likely be stuck tight in the guides. There very likely will be corrosion on the lifters, they may be stuck and the cam likely damaged.
Personally, I would not try too hard to salvage the head, certainly not the valve gear. IF the valves can be driven from the guides, its possible the bare head might be salvaged.
First thing I would do is pull the engine, I would not even think about taking it apart in the truck. To my mind that would be a total waste of time as it will all have to come apart, right down to the bare block. Every part will need to be inspected for rust damage.
There will be a lot of damage. Pretty sad to see that picture.
