Oh my goodness! I have only seen smoke that bad when PDad burned his tires!

yeah. that is steam actually. My car makes more steam than the average old school steam locomotive

You don't have a cracked head. That'* nearly impossible on a 3800 of any generation. You have bad LIM seals more than likely. One afternoons worth of work. Fixing before selling, or selling as is, or keeping it now?

notice steam comming out of lower part of engine:

I dont think it is too safe to drive like this.

Is the steam from below the exhaust manifold indicative of a blown head gasket?

No, it'* indicative of cracks in the exhaust manifolds. Typical for 92-94 L27'*, and even more so for 92-95 L67'*.

My 90% bet is on bad LIM seals and cracked EM'*. Especially with alot of coolant flowing, it heats and cools the EM'* far too quickly. And the recent overheating, as well.

I beg to differ.

And you're trying to show me WHAT? I see steam/smoke coming from the vicinity of the front 3 cylinders. I see nothing to disprove what I mentioned above.

um, there is a LOT of steam comming out.
