The Cometic .027in MLS head gasket designed for the Chrysler R3 race block features a 4.185in bore and fits W7, W8 and W9 heads. Its multi-layer stainless steel construction uses embossed outer layers coated with Viton for thermal and chemical resilience while an uncoated center shim enables thickness control. This MLS design seals high-output engines without sealants, tolerates shear between dissimilar head and block materials, and helps reduce clamp load and bore distortion.
