Broken lifters? I have heard of them splitting down center, or crushing. Perhaps they are were jammed after they broke.
What I would do is start the truck, and put your finger directly on the end of the push rod and feel it to see if it is moving at all. If it is moving a tiny bit, it might be the hydraulic part that has collapsed. This could be an oil pressure problem (like a clogged gallery) or possibly from a broken lifter.
