Worst of all, it's her daily driver; she needs it.
I have a HF compression tester that I was planning on using on it, because it's so hard (if not impossible) to start the thing up during these cold mornings. However, going through the trouble may just seem like a moot point now considering all other factors.

Try and fix it? Or sell as a parts car?
Don't waste time...

Take the car to a repair shop for a cooling system pressure test.

If there is no external leak = 99.9% odds the head gasket is bad.

If you continue driving with a bad head gasket = begging for more damage or catastrophic failure.

After 34 years, the head gasket is IMO an expected maintenance item.

The DIY requires few special tools.
