The Cometic MLS head gasket for the Chrysler R3 race block is a .045in multi-layer steel unit with a 4.165in bore, made for W7, W8 and W9 heads. It delivers high-sealing reliability without sealants for high-output engines. Constructed from multiple embossed stainless steel layers, the outer faces are Viton-coated while an uncoated center shim handles thickness, reducing clamp load and resisting corrosion and shear between dissimilar head/block materials.
