What is a remanufactured cylinder head? 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. Is it always necessary to remove a cylinder head to repair it? No. The following repairs can be made without removing the cylinder head(s) on most vehicles: - Replacement of camshaft & camshaft seals (OHC)
- Valve stem seals
- Lifters (OHC)
- Hydraulic lash compensators (OHC)
- Cam followers (OHC)
- Valve springs
- Rocker arms
What are the advantages of purchasing a remanufactured cylinder head over of a new cylinder head? 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. What should I expect to pay for a remanufactured cylinder head? Prices vary from $125.00 (cast iron OHV cylinder head) to as high as $460.00 (DOHC aluminum cylinder head). Your cost will fall somewhere in between, depending on the type of cylinder head.
