The Cometic MLS cylinder head gasket for Chevrolet Gen‑1 Small Block V8 (4.165" bore, 0.089" compressed thickness) is a multi-layer stainless steel gasket finished for round‑bore, 18/23° heads and fitted with steam holes. Its embossed outer layers are coated with Viton and AMP while a stainless shim layer provides controlled thickness and rebound. The gasket seals aluminum-to-aluminum or aluminum-to-cast-iron joints without sealants, resists corrosion and helps reduce clamp load-induced bore distortion.
