      Description

      High-Performance Exhaust Seal. The Mr. Gasket 1955-1991 Small Block Header Gaskets Gen I are designed to provide a reliable seal between the cylinder head and exhaust headers. These gaskets ensure optimal exhaust flow and help prevent leaks that could impact engine performance and efficiency, making them suitable for both street and race applications.

      Durable Construction. Made from a high-temperature steel core combined with a graphite-faced layer, these gaskets offer excellent heat resistance and conductivity. The expanded steel core improves stability and torque retention, while the graphite facing transfers heat away from the cylinder head, helping to protect engine components.

      Easy Installation. Designed as a direct replacement for OE headers, these gaskets conform to minor surface imperfections to maintain a secure seal, simplifying installation on compatible engines without requiring drilling or modification.

      Warranty and Application. Backed by a manufacturer’s limited 90-day warranty, these gaskets fit Chevrolet Small Block Gen I engines made from 1955 through 1991, featuring square ports measuring 1.45 x 1.48 inches.
