I called one of the listed shops and asked for an estimate on replacement of a head gasket. they told me they don't replace the head gasket but would only replace the ENTIRE ENGINE because something caused it to fail and it would be better if the whole thing was replaced. Is there ANY validity to that?

I would take it somewhere else. There is no reason just a head gasket cannot be replaced. At worst the head could be warped but a warped head can often be machined. If not it can be replaced.
Well, apparently the person who owned the truck before me NEVER changed the oil. After taking it in and getting it looked at by one of the most reputable mechanic shops in my area the head was cracked and spun out a bearing. He said I was lucky to make it home from my 1000 mile journey. Whoopie, 6k later and I have a new engine.
