Cometic MLS cylinder head gasket for Chevrolet Mark‑IV big block V8, 4.320" bore and .060" compressed thickness. The MLS construction uses multiple embossed stainless steel layers with Viton‑coated outer faces and an uncoated shim layer for controlled thickness and corrosion resistance. MLS gaskets provide strong sealing without sealants, reduce clamp load and bore distortion, and conform load distribution to resist shearing between aluminum and cast‑iron or aluminum components.
