The Cometic MLS head gasket for Chrysler R3 race blocks is a .120 in multi-layer steel cylinder head gasket with a 4.100 in bore for W2 heads; compressed operating thickness is noted as 0.036 in. Its embossed outer stainless layers are Viton-coated to withstand harsh sealing environments while an uncoated stainless shim layer sets thickness. MLS design resists corrosion, rebounds under load, and seals without sealants.
