The set includes valves, springs, retainers, keepers and seals — everything needed to repair the head's valve mechanism.
They should be replaced if the valves are burnt, compression is lost, the springs are weak, or oil leaks along the stems. It is convenient to buy the set so you can renew the whole mechanism at once.
