Sounds like a blown head gasket to me. After you install a new head gasket,
you need to run the car up to normal operating temp and then retorque the
head. Once the car overheated, the gasket got contaminated by engine fluids
and no longer seals properly. Unless you're using a copper head gasket, the
gasket is hosed.
