What is a Cylinder Head?

From Wikipedia: “In an internal combustion engine, the cylinder head (often informally abbreviated to just head) sits above the cylinders on top of the cylinder block. It closes in the top of the cylinder, forming the combustion chamber. This joint is sealed by a head gasket. In most engines, the head also provides space for the passages that feed air and fuel to the cylinder, and that allow the exhaust to escape. The head can also be a place to mount the valves, spark plugs, and fuel injectors.”

How much does a used cylinder head usually cost?

The cost of a cylinder head ranges from $100 to $400.

Things to keep in mind when buying

If its an OHC (Overhead CAM) make sure that it includes the cam and that it is still assembled. Make sure it can be returned before installation if it is determined to be slightly warped or cracked. If possible match the casting number to your head. This is not 100% required but does ensure an exact match.

Installation Tips

Always get a valve job done and the cylinder head surface and pressure tested

Ongoing maintenance

Change your oil regularly and drive safe!
