    the more you drive it, the more damage you do to the motor.
    you need a shop to do a leak down test to confirm the number of cylinders effected by the failure. then they can give you a bid based on ther results.
    then after this is done, they need to find the original issue as to why it overheated. the head gaskets are a result of the overheating not the reason for overheating.

    it will be costly to the point that it may require a new or rebuilt motor.

    thanks for using repairpal
