Cometic’s big-bore head-and-base gasket kit for Indian Chief (2014–2015) is sized at 4.252 inches with a .040-inch MLS head gasket and .014-inch base gasket. The MLS construction features embossed layers to meet harsh sealing conditions and the stainless shim center that can be varied for thickness needs. This design helps distribute load, reduce bore distortion and avoid the need for sealants or re-torquing.
