The graphite cylinder head gasket material offers excellent heat resistance and conforms well to surface irregularities, reducing the risk of leaks. The exhaust manifold gasket uses multi-layered steel to withstand high temperatures and prevent exhaust leaks.

This set includes various miscellaneous gaskets and seals necessary for a complete engine sealing solution but does not include cylinder head bolts.

Applications and Common Issues Addressed

Installation Notes and Tips

Ensure the cylinder head and engine block surfaces are clean and free of debris before installation. Use the torque to yield specification when tightening bolts to achieve proper clamping force and avoid gasket damage. Since cylinder head bolts are not included, reuse existing bolts if they are in good condition or replace them separately. Follow manufacturer torque sequences and specifications for best results.
