Cylinder head gaskets (sealing rings) play a critical role in containing combustion pressure and heat. They ensure a gas-tight seal between the cylinder and head, supporting stable compression, efficient combustion, and consistent engine performance across all six cylinders.

Replacing all six gaskets at once ensures uniform sealing and balanced compression throughout the engine.

Function:
• Seals the cylinder-to-head interface under extreme heat and pressure
• Maintains compression integrity for efficient combustion
• Prevents blow-by and gas leakage at the head joint
• Protects cylinder heads and barrels during long-term operation

Correct sealing is essential on air-cooled engines, where thermal expansion and operating temperatures place high stress on the head-to-cylinder joint.

Cylinder head gaskets are exposed to extreme thermal and mechanical stress. Over time, sealing rings can lose effectiveness, leading to:
•  Compression loss
•  Combustion gas leakage
•  Reduced engine efficiency
•  Risk of head or cylinder damage.

Replacing all six gaskets during a rebuild or top-end refresh ensures consistent sealing, protects machined surfaces, and supports long-term engine reliability.

When to replace. Replace cylinder head gaskets when:
•  Performing a top-end rebuild or engine overhaul
•  Cylinder heads are removed
•  Leak-down or compression tests show sealing issues
•  Evidence of combustion leakage is found
•  As preventative maintenance during engine restoration
