Cometic’s ‘MLS’ (Multi-Layer Steel’) gaskets are 3-piece head gaskets that are made up of a stainless steel center sandwiched by two viton-coated spring steel embossed outer layers for a seal that can withstand the shearing forces created in the head gasket environment. Non-intrusive rivets hold the combination together. Sold in 2 different thicknesses, .040” (standard) and .030” (high compression). Piston-to-head clearance should be verified (.030”-.032” optimum) before using .030” gaskets. Sold in pairs.
Cometic® "SLS" (Single Layer Steel) .020" base gaskets are made from spring steel for durability, with a .001" thick layer of viton rubber on both sides for improved leak resistance. Sold in pairs.
