Add the plastic tanks on the radiator and those are the most common leak areas on that engine. I can't say I have ever seen a head gasket on a 350 go bad without severe overheating first.

What would the heater core and hose connections do to cause the dirty/cloudy coolant?
The truck is fairly new to me but has not overheated since I've owned it. No idea what the previous owner may have done to it though.
