•  Position on Vehicle: All valve positions across the engine’s cylinder heads where intake/exhaust guides are located.

• Applications: Recommended when undertaking a full head rebuild, especially after seat machining, guide bore wear or when aiming for consistent component age across all cylinders.

Replacing all valve guides together ensures even wear characteristics, consistent valve movement and avoids mixing new guides with old worn ones which may compromise engine balance or longevity.

When to replace full set:
•  Full cylinder head rebuild including seat work, milling or guide bore enlargement.
•  Engine showing symptoms of widespread valve guide wear (smoke, oil consumption, play) across multiple cylinders.
•  When aiming for maximum long-term reliability and standardised new parts across the engine.
