Chevrolet Performance cylinder head gaskets, cylinder head bolts and cylinder head studs are the finest-quality parts available. Their superior construction ensures optimum sealing between cylinder heads and the engine block.

Chevy Gasket packages contain one gasket unless otherwise specified. Head gaskets are available in a variety of materials and thicknesses. GM engineers recommend using the proper gasket to maintain compression ratios and minimum piston-to-cylinder-head clearances.
