The Cometic .036in MLS head gasket for the Chrysler R3 race block lists a 4.185in bore and fits W7, W8 and W9 heads; compressed operating thickness is 0.036in and World Products Man-o-War block compatibility is noted. Multiple embossed stainless steel layers provide strength, with Viton-coated outer faces for heat resistance and an uncoated center shim to tailor thickness. The gasket seals without sealants, handles shear between materials and helps reduce clamp load and bore distortion.
