The Cometic MLS cylinder head gasket for the Chrysler R3 race block is a .098-inch multi‑layer steel gasket with a 4.185-inch bore specified for W7, W8 and W9 heads. Its embossed outer stainless layers are coated with Viton to withstand high temperatures and harsh sealing environments; the center shim is uncoated stainless steel. MLS construction provides robust sealing without sealants, reduces required clamp load and helps conform load distribution across the sealing area.
