The MLX head gaskets are multi-layer stainless steel for increased strength and require no sealants or re-torquing. They also have an integrated “stopper” layer for optimum combustion chamber sealing and improved clamp load around the cylinder without increasing bore distortion. The gaskets are for .030″ overbored cylinder bores (3.875″) and have a compressed thickness of .058.”
