The Cometic MLS head gasket for Chrysler R3 race blocks is a .040 in multi-layer steel cylinder head gasket with a 4.060 in bore for W2 heads; compressed operating thickness is specified at 0.036 in. Embossed stainless outer layers are coated with Viton for heat-resistant sealing while an uncoated stainless shim layer controls thickness. MLS construction seals without sealants and helps distribute clamp load to reduce bore distortion.
