Cometic MLS gaskets create a chemical bond with the cylinder head and block surfaces during the first heat cycle, providing superior sealing performance. The multiple stainless steel layers increase active seal height and resist corrosion while rebounding to maintain seal integrity. These gaskets require smooth, flat surfaces and cannot be used with O-ringed or grooved cylinder bores.
