So what exactly does that mean? How does that happen, cracked head? What effect does this have on the engine?

Is it a gonner?

It means either the head has a crack or the head gasket is blown. Pull the head & look @ the head gasket between each cylinder. If there's any area that looks like the material has been breached, that's your answer. No breaches.... have the heads checked @ a local shop.

For what it's worth..... If your going to do it, do it right. Pull both heads & replace both head gaskets @ the same time. If you can, get the heads 'rebuilt' or replace them w/the Vortec kit you mentioned earlier.

The residue that was on your finger does look suspect. If it's light in color, chances are it's a blown head gasket.

You need to see if there's coolant in any one of the cylinders. Too much coolant & the cylinder will 'hydraulic', which means it won't compress the combustion mixture as intended & can bend valves, rods, or do other general damage.

Now the question is...how long was it run like this?

damn man, doesnt look so good. Good luck with the vortec stuff, should wake the truck up pretty good. How about a little clean up in the engine bay

I have a set of long tubes you could put on that thing too if you are interested. I took them off when I did the 5.3 swap in my truck.
