The Cometic MLS cylinder head gasket for Chevrolet Gen‑1 Small Block V8 (4.200" bore, 0.092" compressed thickness) suits round‑bore, 18/23° heads and includes steam holes. Built from multiple embossed stainless layers with Viton/AMP coatings and a stainless shim center, it offers rebound, corrosion resistance and precise sealing thickness. It is intended for aluminum-to-aluminum or aluminum-to-cast-iron sealing without sealants and helps reduce clamp load-induced bore distortion.
