Installation Notes and Tips

Confirm cylinder head surface condition, block flatness, and bore alignment before installation.

Follow the engine manufacturer’s tightening sequence, torque stages, and final specifications exactly. Clean all mating surfaces thoroughly and do not apply sealant unless the engine service procedure specifically calls for it.
