Most cylinder heads are salvageable and comparatively inexpensive to repair. A remanufactured cylinder head often costs less than half the price of a new one. A remanufactured cylinder head is a head that has been rebuilt with parts that are still serviceable. Most heads have been welded or repaired. All heads are pressure tested to assure a leak-free casting. New valve seats have been installed when needed. All heads have a three angle valve cut with a blade type seat cutter. Valves are ground to factory specifications or replaced if necessary. Valve springs are checked. Cylinder heads are painted, resurfaced, and reassembled.
