This Cometic MLS head gasket is specified for GM Gen-4 small block V8 engines with a 4.185in bore and .086in compressed thickness, featuring parallel cooling. The MLS construction uses multiple embossed outer layers coated with AMP and uncoated stainless shim layers at the core. Embossed outer layers coated with Viton-style materials conform to varied sealing surfaces, distribute clamp load evenly, and reduce bore distortion while meeting demanding sealing and load conditions.
