The Cometic MLS cylinder head gasket for the Chrysler R3 race block is a .120-inch multi‑layer steel gasket with a 4.185-inch bore for W7, W8 and W9 heads. Embossed outer layers are coated with Viton to resist heat and chemical exposure, and the uncoated stainless shim layer allows precise thickness control. MLS gaskets seal high‑output engines without sealants, tolerate material shear between heads and blocks, and help distribute clamp load to limit bore distortion.
