The Cometic MLS exhaust header gasket set for Chevrolet Gen‑1 Small Block V8 (.030in) specified for All Pro heads uses multiple embossed AMP-coated and uncoated stainless steel layers for extreme sealing without sealants. Its embossed outer layers meet harsh sealing and surface finish demands while the uncoated center shim can be varied for thickness, reducing required clamp load and limiting bore distortion.
