Mr Gasket 5912 Exhaust Gaskets, Big Block Chevy, 2.15 Inch

- Manufactured from high-temperature steel core/graphite faced exhaust material.

- Expanded steel core provides stability and maximum torque retention to eliminate gasket failure.

- Graphite facing provides excellent heat resistance and thermal conductivity to transfer heat away from the cylinder head.

- Conforms to and seals minor surface irregularities. High recovery material allows header or manifold flange to stay sealed if flange loses clamp-load.

- Can be trimmed if necessary for modified port applications.

- For OE replacement, high performance street, drag race and oval track use.
