Cometic MLS exhaust gaskets are multi-layer steel designs built to withstand extreme cylinder pressures and differing head/manifold materials. This .030" MLS gasket features a 1.850" x 1.900" port and embossed AMP-coated outer layers over an uncoated stainless center shim for reliable sealing without sealants. MLS construction resists burn-through, maintains torque set, and reduces clamp load to limit bore distortion for GM Big Block V8 applications.
