The Cometic MLS cylinder head gasket for Chevrolet Gen‑1 Small Block V8 (4.165" bore, 0.098" compressed thickness) suits round‑bore, 18/23° heads and includes steam holes. Multi-layer stainless steel construction pairs embossed Viton/AMP-coated outer layers with an uncoated shim to control thickness, rebound and corrosion resistance. It seals aluminum-to-aluminum and aluminum-to-cast-iron interfaces without sealants and helps distribute clamp load to limit bore distortion.
