Engineered for performance and durability, these replacement head gaskets use a multi-layer construction with an extra stopper fold-over layer that provides a torque-limiting surface to protect the combustion seal. 🔧

  • Proprietary high-temperature coatings and precision embossments form a micro-seal against the head and block surfaces.
  • Ideal for Milwaukee 8 applications running turbo, high-compression, nitrous, or other power-adder modifications.
  • Requires no special machining and installs like a standard multi-layer steel gasket.
  • Designed to fit both air/oil-cooled and twin-cooled heads for reliable long-term performance.
  • Manufactured in the USA to strict quality standards.

These gaskets deliver consistent sealing under extreme pressures and temperatures so you can focus on power and reliability.
