Selection Guidance
Fastener preload supplies the clamping force at the head-to-block joint. Gasket sealing also depends on suitable deck finish, component condition and the correct assembly procedure.
Match the engine and any specified aftermarket cylinder heads or block to the listed configuration. Do not assume that related engines use the same fastener dimensions. Pay particular attention to the stated with 18A Chevrolet Heads configuration.
Installation Considerations
Check block threads, fastener engagement and cylinder-head clearance during trial assembly. Follow the instructions for this exact part number, including lubricant locations, washer orientation and tightening sequence. Washer seating and lubrication requirements vary by kit.
