The Cometic MLS cylinder head gasket for Chevrolet Gen‑1 Small Block V8 (4.165" bore, 0.095" compressed thickness) is specified for round‑bore, 18/23° heads and supplied with steam holes. It uses embossed outer stainless layers coated in Viton/AMP and a center uncoated shim for precise thickness control. The multi-layer steel construction resists corrosion, tolerates mixed-metal shearing, seals without additional sealants, and reduces clamp load‑related bore distortion.
