If all else fails, heck, pass the nitrous bottle and let's get funny. But either way, the dudes at Mr. Gasket have got us covered with a new line of Multi-Layered Steel (MLS) exhaust and header collector gaskets, designed for extreme cylinder pressures produced by high-horsepower, high-compression turbocharged, supercharged and nitrous oxide engines. Manufactured from three stainless steel layers, they resist corrosion, and they 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 excessive exhaust pressure. The gaskets withstand different combinations of cylinder head (aluminum) and exhaust header or manifold (steel) materials, and will not deteriorate from scrubbing action caused by different expansion rates in aluminum and steel material. Applications include Chevy 350 small-blocks (square- or round-port), LT1 and LS motors, square port Chevy 454s, and Ford rectangular-port 302s. Log onto Mr. Gasket's website for more info.
