The Cometic MLS cylinder head gasket for Honda B18A1/B18B1 (.018") fits an 81.5mm bore and uses embossed stainless steel outer layers coated with Viton plus uncoated shim layers. The multi-layer design rebounds to resist corrosion and shearing between head and block materials. No sealants are required; the gasket reduces required clamp load and helps limit bore distortion while providing consistent sealing for high-output or rebuilt engines.
