The Cometic MLS head gasket for Chevrolet Gen‑1 Small Block V8 (4.080" bore, 18/23° heads, with valve pockets) uses multiple embossed stainless steel layers with Viton‑coated outer faces for heat and corrosion resistance. Compressed operating thickness is 0.036" and it seals high‑output engines without sealants. Its layered construction rebounds under load, reduces required clamp load and bore distortion, and suits aluminum‑to‑aluminum or aluminum‑to‑cast‑iron assemblies.
