Header Gaskets - MLS - 262-400 Chevrolet Small Block Gen I 1955-91

• Multi-Layered Steel (MLS) exhaust and header collector gaskets are designed for extreme cylinder pressures produced by high horsepower–high compression turbo-charged, supercharged and nitrous oxide injected engines. • Manufactured from three stainless steel layers, they resist corrosion, will not burn through or push out and maintain maximum fastener torque retention. • Stress formed inner and outer layer embossments act like springs that rebound under exhaust flange clamp load, creating force to seal extreme exhaust pressures. Total gasket thickness .075 ̋. • Will not deteriorate from scrubbing action caused by different expansion rates in aluminum and steel materials.
