The Cometic Gen-2 Hemi MLS head gasket for Chrysler Gen-2 Hemi engines with a 4.280in bore is a multi-layer stainless head gasket built for strong sealing in demanding, high-output applications and requires no sealants. Outer embossed layers are coated both sides with Viton while the center shim is uncoated stainless to allow thickness variation. The MLS construction rebounds under load, resists corrosion and helps distribute clamp forces; compressed operating thickness is recorded as 0.140in nominal in source.
