The Cometic MLS head gasket for the Chrysler 6.1L Gen-3 Hemi is a .040" thick multi-layer steel gasket sized for a 4.055in bore and specified for aluminum-sleeved blocks. Outer embossed layers are coated with Viton for heat resistance and sealing performance, and the uncoated stainless center shim accommodates thickness requirements. It’s engineered to provide robust sealing for high-output Hemi applications without the need for sealants.
