I just finishing reading a thread from 2013 on this problem with 239 V8 flat head engine. But it has lead to more questions. Specifically;
1. How do you which head goes on which side? Are there markings on the head?
2. How do know which head gasket goes on what side, and what side should face the block verses the head?
3. Is there a way to see if one of the water pump is not doing operating properly?

There is no sign of coolant in the oil, and no smell or vapor coming from the exhaust. It seems as if its all going out thru the overflow.
I will be checking all of the suggestions: timing, spark plug condition, compression and testing each side for a temperature variant.

 

Your post is a little confusing. Does your truck have a flathead in it for some reason?

 

looks like my post ended in the wrong section.
