Product Details

FlowTech Exhaust 99150AFLT aluminum-layered header gaskets provide a superior sealing solution for 1955-1991 Chevrolet Small Block Gen I engines (262-400 cubic inch). These multi-layer gaskets are engineered to eliminate exhaust leaks and withstand the extreme temperatures and pressures of performance exhaust systems.

Key Features:

  • Multi-layer "dead soft" aluminum construction conforms to head and header surfaces for a leak-proof seal
  • Reusable design allows for multiple installations without degradation
  • Will not burn out or blow out under high-temperature exhaust conditions
  • Water and weather resistant for long-lasting durability
  • Suitable for port-matching applications to optimize exhaust flow
  • Made in USA with quality materials and manufacturing

These header gaskets are ideal for street performance, racing, and restoration applications where reliable exhaust sealing is critical. The flexible aluminum layers compress evenly to accommodate minor surface imperfections and maintain a consistent seal through heat cycles.
