Did it overheat immediately after the first repair? If it did and you never brought it back, then you have the liability from driving it overheated. Driving it overheated caused the head gasket issue.
If it was ok for the 4 weeks, then you had a new problem surface.
No matter what, you need it fixed. 4200 is way too much money for head gaskets. Did you get a second opinion or another bid for the job?
