      Description

      High-Performance Header Gasket. The Mr. Gasket 1965-1990 Big Block Header Gaskets provide a reliable seal between the cylinder head and exhaust header, preventing exhaust leaks. Designed for use in high-performance applications, these gaskets are essential for maintaining engine efficiency and preventing loss of power or damage caused by escaping gases.

      Construction and Appearance. Made from a high-temperature steel core combined with a graphite faced exhaust material, these gaskets feature an expanded steel core for enhanced stability and torque retention. The graphite facing offers excellent heat resistance and thermal conductivity, providing a durable seal that also helps dissipate heat from the cylinder head.

      Installation. Installation typically involves removing the old gasket and replacing it with this one. The gasket fits precisely to the designated port size and shape, with the option to trim if necessary for modified port applications.

      Warranty. This product is backed by a manufacturer’s limited 90 day warranty.

      Application. Specifically designed to fit 1965 through 1990 Chevrolet and GMC Big Block Mark IV engines with 2.40 inch round ports. This gasket is suitable for original equipment replacement as well as high performance street, drag race, and oval track use.
