I tend to agree with your steps and conclusion. Sounds like head gasket all the way. another tel tale sign of that is greater than usual amounts of white smoke coming from the tail pipe with a distinctive antifreeze smell. Your pics are great. Only sorry you had to take them in the first place. :o((
When you are able, think about replacing all the hoses in your pics, most of them are in bad shape.
