The Cometic MLX head gasket for GM LS-series small block V8s uses multiple embossed stainless steel layers with Viton-coated outer faces and an integrated stopper layer for combustion sealing. With a .040" compressed operating thickness and a 4.040" bore, MLX construction provides strong rebound, corrosion resistance and improved clamp load distribution for high-output engines, eliminating the need for sealants in aluminum-to-aluminum or aluminum-to-iron applications.
