The Cometic MLS cylinder head gasket for Honda B20B4 and B20Z2 engines is a .050in gasket with an 85mm bore designed for high-output sealing. It uses three to five layers of stainless steel with embossed outer layers coated in Viton and an uncoated stainless shim center. The gasket requires no sealants, tolerates aluminum head to aluminum or cast-iron block interfaces, resists corrosion and helps distribute clamp load to reduce bore distortion.
