      Description

      Superior Exhaust Sealing. The Mr. Gasket 1955-1991 Aluminum Header Gaskets GEN 1 283-400 with Round Ports provide a reliable solution to exhaust gasket failure by offering a durable, leak-proof seal. These gaskets are designed for use on high-performance and street engines, ensuring long-lasting performance by conforming perfectly to imperfect flange surfaces. They are essential to maintaining exhaust integrity and preventing leaks that can reduce engine efficiency and performance.

      Construction and Appearance. These header gaskets are crafted from dead soft aluminum layered material measuring 0.125 inches thick. The aluminum offers excellent heat resistance and the flexibility needed to conform to warped or damaged flange surfaces. The flat finish ensures a consistent, smooth sealing surface that aids in creating an airtight seal and simplifies installation and removal.

      Installation. Installation is straightforward and requires no drilling, as the gaskets are designed to fit existing bolt patterns and manifolds. Their compressibility allows them to seal uneven surfaces effectively without additional modifications.

      Warranty. These gaskets come with a manufacturer’s limited 90-day warranty.

      Application. Specifically designed to fit Chevrolet Gen I Small Block engines ranging from 262 to 400 cubic inches, equipped with round ports, and produced between 1955 and 1991.
