Cometic MLS-5 head gasket for Chevrolet Gen-1 small-block V8 with a 4.200-inch round bore, .060-inch compressed thickness, and all steam holes included. Multiple embossed stainless-steel layers use Viton coating on outer faces while the center shim is uncoated stainless steel for thickness control. MLS construction needs no sealants, resists corrosion and shearing between different materials, conforms load across the sealing area, and helps prevent bore distortion.
