Cometic MLS cylinder head gasket for Chevrolet Gen‑1 small block V8, 4.200" bore and .051" compressed thickness, suitable for Brodix 12–23° aftermarket heads with undersized water ports to allow customization. The MLS construction uses embossed, Viton‑coated outer layers and an uncoated shim layer for thickness control and rebound. MLS gaskets require no sealants, help reduce clamp load and bore distortion, and provide reliable sealing across aluminum or cast‑iron mating surfaces.
