Wish I could diag this car in person.

I ran a block test on it today and block testing fluid did not change color so as far as I can tell the head gasket is fine, while I had the coolant partially drained I decided to take a look and see if coolant was flowing as it should with the thermostat open....as far as I could tell the coolant wasn't really flowing so much as it was just collecting in the fill neck even after revving the engine up to about 2500rpm....seems like pressure just builds in the system, but coolant isn't really flowing much.
