The Cometic .066in MLS head gasket for the Chrysler R3 race block is specified for a 4.185in bore and W7, W8 and W9 heads; compressed operating thickness is 0.036in and World Products Man-o-War block fitment is mentioned. Multiple embossed stainless steel layers with Viton-coated outer faces provide heat resistance and corrosion protection, while an uncoated center shim allows thickness variation. It seals without sealants, handles shear between materials and reduces clamp load to limit bore distortion.
