Cometic MLS head gasket for Chevrolet Gen‑1 Small Block V8, 4.080in bore with .066in compressed thickness for Vortec heads. Constructed from multiple stainless steel layers with embossed, Viton‑coated outer faces, it resists heat and corrosion and rebounds under load. The uncoated center shim permits thickness variation. This MLS design seals high‑output engines without sealants and manages the shearing forces produced by differing head and block materials.
