Fixing a head gasket can be worth its price based on the age of your vehicle and the damage that has been done. Engine blocks, water pumps, heater cores, and many other components can be damaged because of blown head gaskets. Therefore, a mechanic will need to closely inspect your vehicle to see what it needs. In many cases, a head gasket repair, a radiator flush, and a few other services are all that are needed to repair the vehicle. However, there are also many blown head gasket cases where overheating led to irreparable damages to engine blocks, cylinder heads, and more.
