The Cometic MLS head gasket for Oldsmobile Gen‑2 Rocket V8 uses embossed stainless outer layers with Viton coating and an uncoated stainless shim to provide a resilient seal for high-output engines. This .120in gasket fits 4.200in bore engines, resists corrosion and shearing at dissimilar-material joints, conforms load distribution across the sealing area, reduces required clamp load, and is specified for installation without sealants.
