Cometic MLS head gasket for GM LSX Gen‑4 small block V8 with a 4.125" bore and nominal .060 in thickness, left-hand side. Designed to seal high-output engines without sealants, it works on aluminum-to-aluminum and aluminum-to-cast-iron interfaces. The gasket stacks embossed stainless steel layers with Viton-coated outer faces and an uncoated shim to provide corrosion resistance, even load distribution and reduced required clamp load to help control bore distortion.
