The mechanic is probably correct in that the issue is simply a head gasket.
However, the head could also be cracked from a previous overheat and the limited symptoms wouldn't manifest themselves to a point where the owner takes any action.
As mentioned, it's all conjecture anyway. When you remove the head, you'll have your answer.

Before the runaway, the cooling system worked perfectly. The car ran great, except for it couldn't get out of it's own way power wise.
The car hadn't been overheated in a very very long time, so that isn't an issue. One thing that concerns me is the sound of the engine at idle.
The head is going to come off soon, and I'll post the updates on that when it happens.
