Everything needed to restore a cylinder head to like-new condition, including basics such as:

• Cleaning cylinder head and valve train components

• Inspecting head for cracks, leaks, warpage, or other damage

• Inspecting valves, seats, springs, guides, and other valve train components for wear and damage (and replacing parts that cannot be reused)

• Grinding or cutting valves and seats

• Restoring valve guides by knurling, relining or replacing, or reaming guides and using valves with oversized stems

• Checking installed valve stem height, spring height and tension, etc., and reassembling the head with new valve guide seals and any other required parts

• Resurfacing head to assure flatness and a proper seal

• The following "extras" might be required, especially on overhead cam aluminum heads:

• Repairing leaks or cracks

• Straightening

• Overhead cam line boring

• Repairing threads

• Replacing seats

There is no such thing as a "standard" valve job. Every job is different. An overhead cam aluminum head may require a lot more time and effort than a cast iron head off a pushrod engine. There is often no way to tell what a head will need in terms of repairs until it has been cleaned, disassembled and inspected.

Exhaust valves and springs often need to be replaced. Valve guides and/or seats may have to be replaced. The head may be warped or cracked, requiring additional repairs. The list of things included in a "complete" valve job will vary from job to job.
