Cometic SBC MLS Head Gasket - 4.200" Bore - .040" Thick - Without Steam Holes

Cometic MLS head gaskets are constructed from multiple layers of stainless steel for strength and contain load-controlled embossments that conform load distribution across the sealing area. This creates an exceptional seal by requiring less clamp load--resulting in less bore distortion. The stainless steel outer layers are coated with FKM (Viton®), a high-temperature and chemical-resistant polymer. A topcoat of PTFE aids in resistance to fret and increased cold sealing. MLS head gaskets are available for most aftermarket cylinder heads; as with all of Cometic's MLS head gaskets, no sealants or re-torque is required.
