This Cometic MLX multi-layer steel head gasket is specified for GM LSX Gen-4 small block V8 engines with a 4.200" bore and .054" thickness. MLX technology uses an integrated stopper layer for combustion chamber sealing and embossed stainless outer layers coated with Viton to resist heat and corrosion. Designed to provide improved clamp load without increased bore distortion, these gaskets require no sealants or re-torque.
