The Cometic MLS head gasket for Honda H23A applications is a .070 inch multi-layer steel (MLS) gasket with an 87.5mm bore intended for high-sealing performance in modern engines. It uses multiple embossed stainless steel layers with outer Viton-coated surfaces and an uncoated stainless center shim to manage thickness and sealing. The gasket is designed to rebound, resist corrosion, and provide reliable sealing between head and block without additional sealants.
