Cometic MLS head gasket for 2001–2006 GM 6.6L Duramax engines with a 4.100" bore and 0.027" compressed operating thickness; right-side piece. Constructed from multiple embossed stainless steel layers with Viton-coated outer faces and an uncoated stainless shim core, it seals high-output diesel engines without sealants. The MLS stack resists corrosion, rebounds under load, tolerates mixed-metal interfaces, and evens clamp forces to reduce bore distortion.
