The Cometic MLS head gasket for Subaru EJ20 (.045 in, 103mm bore) is a multi-layer stainless steel cylinder head gasket designed to seal high-output engines without sealants. It is suitable for aluminum-head pairings with aluminum or cast-iron blocks. The gasket combines embossed stainless steel outer layers coated with Viton for heat resistance and an uncoated shim center for thickness variation, giving rebound, corrosion resistance, and improved load distribution to limit bore distortion.
