Sounds like a bad headgasket to me

1 buddy said that and another said it was bad gas

Pressurize the cooling system with a radiator tester. Pressure should hold if not bad head, gasket, Bad gas will just make it run like ****.

It's sat for long enough that I wouldn't blame the head gasket right away.

Get some new gas in it (maybe pull the old stuff out and mix it with gas in some other vehicle), run it for a while and see what happens.
