• Precise machining for grooves in the block and head is essential. We recommend a radiused cutter for all installations.
• It is imperative to verify that the head and block are flat to ensure proper sealing and to prevent gasket failure.

Installation:

• Apply a generous amount of lubrication to the nuts, washers, and threads of the studs to ensure consistent clamp load across all studs, preventing uneven pressure on the gasket that could lead to failure.
• Avoid exceeding the torque specifications provided by the manufacturer, as doing so can compromise the integrity of the fasteners.
• For initial installation, torque the fasteners to approximately 130 ft/lb, and then bring the engine up to operating temperature.
• After reaching operating temperature, perform a hot retorque to ensure all fasteners maintain proper tension.
• It is advisable to check the valve lash after each torque sequence, as retorquing may compress the head gasket and affect valve clearances; always re-check the torque before operating the engine at full load or RPM.
