Cometic MLS head gasket for Chrysler R3 race block, 0.030 in thickness with a 4.100 in bore, compatible with W7, W8 and W9 heads. Engineered to seal high-output engines without sealants, it suits aluminum heads on aluminum or cast-iron blocks and withstands shear between different materials. Embossed stainless outer layers are coated with Viton for heat and chemical resistance, while a central uncoated stainless shim permits thickness control. The design reduces required clamp load to limit bore distortion and improves load conformity across the sealing area.
