5. Revised Port Design

The 81mm cylinder head has revised intake and exhaust ports that optimize the flow of air and gas. This design results in more efficient combustion and increased power output, thus delivering better performance.

6. Upgraded Cylinder Head Gasket

The new cylinder head gasket is compatible with the 3021124 cylinder head and provides a reliable seal between the engine block and the head to ensure a proper compression ratio and efficiency of the manifold.

In conclusion, the Polaris 3021124 81mm Cylinder Head, with its increased bore size, durable valve guides, enlarged combustion chambers, improved cooling, revised port design, and upgraded cylinder head gasket, is an excellent upgrade for any Polaris 700 RMK snowmobile enthusiast seeking more power, torque, and engine longevity.
