The Cometic MLS head gasket for GM L42/L61 Gen‑1/2 ECOTEC (87mm bore, nominal .098in) combines embossed stainless steel layers with Viton-coated outer faces and AMP for robust sealing in harsh conditions. Compressed operating thickness is 0.098". The uncoated stainless shim center allows adjustment for different stack-ups, helping the gasket resist corrosion, conform load across the sealing area, and seal aluminum-to-aluminum or aluminum-to-iron interfaces without sealants.
