NOTE: Head gaskets are specific for right hand and left hand applications and also must be installed with the correct side facing up. Note the markings (1) on the head gaskets for proper installation. Failure to do so may lead to engine damage.

NOTE: This component uses torque-to-yield bolts. When servicing this component do not reuse the bolts, New torque-to-yield bolts must be installed. Reusing used torque-to-yield bolts will not provide proper bolt torque and clamp load. Failure to install NEW torque-to-yield bolts may lead to engine damage.

Install the cylinder head locator dowel pins, if necessary.
Inspect the cylinder head locator dowel pins for proper installation.
