Fitment
This listing does not name specific vehicles. Match the part number and the specifications with the part you are replacing.
What it does
Valves are usually replaced during a cylinder head rebuild, along with guides, seals and a valve job. Using the correct part for your exact engine keeps oil pressure, sealing and timing where the engine was designed to run, and doing related parts at the same time saves taking it apart twice.
Installation & tips
- Have the valve seats cut or lapped so the new valves seal fully.
- Valve stem seals: Always new with new valves.
- Head gasket: The head comes off for this job.
- Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
