The Cometic .080in MLS head gasket for the Chrysler R3 race block carries a 4.165in bore and supports W7, W8 and W9 heads; compressed operating thickness is 0.036in and it notes World Products Man-o-War block application. Constructed from embossed stainless steel layers with Viton-coated outer faces, the gasket resists corrosion and rebounding forces, requires no sealants, and uses an uncoated center shim to accommodate thickness needs while reducing clamp load and bore distortion.
