The Cometic MLS cylinder head gasket for Chevrolet 348/409 W-Series Big Block V8 (.040in nominal, 4.375in bore) is built from multiple embossed stainless steel layers to provide high sealing performance. Outer layers are Viton-coated for heat resistance and corrosion protection; the center shim is uncoated stainless that can be varied for thickness. The gasket requires no sealants, tolerates mixed-material assemblies and helps conform load distribution to reduce bore distortion.
