Exhaust Gaskets, Header, Ultra-Seal, Steel Core Laminate, Round Port, Chevy, Big Block, Pair
Mr. Gasket Ultra-Seal exhaust gaskets are designed and constructed to improve the sealing of exhaust header flanges. Unlike standard exhaust gasket material, Ultra-Seal gaskets incorporate a graphite-impregnated facing and a steel-expanded metal core that reinforces and increases their tensile strength. This allows the gaskets to conform to warped flanges, giving them better sealing capabilities without deteriorating or cracking under the excessive heat and pressure that's common in exhaust systems. Ultra-Seal gaskets are available for a wide range of port styles and sizes.
Additional features and benefits:
• 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
• High-recovery material allows header or manifold flange to stay sealed if flange loses clamp-load
• Can be trimmed for modified port applications
• Designed for OE replacement, high performance street, drag race, road racing, and oval track use
