Head gasket kit for use with OS SPEED 12TZ SP2

This RC head gasket set fits the OS SPEED 12TZ SP2 engine and is identified as OS21531410 from O.S. Engine. It is intended to renew the sealing surfaces between the cylinder head and crankcase during servicing or rebuilds.

Install this gasket set when you remove the head for inspection, to swap out aged seals, or while performing tuning that requires access to the head. Correct gasket fitment helps keep compression consistent and combustion stable in nitro RC engines.

Fitment tips: thoroughly clean mating faces, inspect for any signs of distortion, and tighten the head bolts in the sequence and to the torque values recommended by the engine maker. Confirm listing details or technical resources if you need to validate compatibility with OS SPEED 12TZ SP2.

Does this kit include all gaskets needed for a head rebuild?

This package is a head gasket set specified for OS SPEED 12TZ SP2. Check the item description to confirm which individual gasket components are included before purchase.

Will using fresh gaskets change engine tuning?

Replacing worn gaskets restores proper compression and can stabilise combustion, which may affect tuning; retune as needed after reassembly to achieve consistent performance.

What if the gasket does not seat correctly?

If a gasket fails to seat, recheck mating surfaces for flatness and cleanliness. Do not force the assembly; resolve any warpage or damage before installing a new gasket to avoid leaks.
