The Cometic MLS head gasket for Honda B20A3/B20A5 is a .030" cylinder head gasket with an 81.5mm bore engineered to seal high-output engines without additional sealants. It uses multiple stainless steel layers with embossed, Viton-coated outer faces for heat and corrosion resistance to 250°C (482°F). The uncoated center shim allows precise thickness control and reduces clamp load and bore distortion.
