Cometic metal ring exhaust flange gasket for GM Gen-3/Gen-4 Small Block LS V8 engines. The multi-layer stainless steel MLS construction with Viton-coated embossed outer layers withstands extreme cylinder pressures and high-temperature environments. It resists corrosion, maintains torque set without sealants, and is designed to prevent burn-through or push-out where different head and manifold materials are used.
