YOU DON'T NEED TO REPLACE YOUR HEAD GASKET.

I don't know about that. But those are sure symptoms. I'd also consider a head gasket replacement if:

There is coolant loss but no leak under the car, and the exhaust smells sweet, or

There is low compression in two adjacent cylinders, or

you need to have the head off for any reason (valve repair, etc.)
