Because more power per cylinder, higher operating temperatures, and thinner head and block castings demand a modified gasket. MLS Gaskets are stronger, more forgiving, and capable of sealing despite movement between the head and block. Such motion results from: lighter, thinner aluminum head castings that are more susceptible to thermal expansion; computer controls that can dramatically increase engine output; reduced clamping force that prevents stress points and cylinder bore distortion.\u003c\/p\u003e\u003cp\u003eMLS Technology was developed to overcome sealing challenges. The number of layers in an MLS Gasket ranges from two to five, depending on the engine's sealing characteristics. Generally, the more layers, the more motion the gasket endures. There are multiple solid layers of heat-treated stainless steel separated by a very thin rubber coating, and the layers are either active (absorbing motion between the head and block) or shim (giving the gasket its correct compressed thickness). Gaskets are sold each.\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003cbr\u003eStainless steel maintains shape\u003cbr\u003eSurvives higher combustion pressure\u003cbr\u003eWithstands \"scrubbing\" between head and block\u003cbr\u003eFunctions at a wider range of operating temperatures\u003cbr\u003eStrategically-placed sealing beads eliminate leak paths\u003cbr\u003e\"Stopper\" layer provides superior primary combustion seal \u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSpecs\u003c\/strong\u003e\u003cbr\u003eBore (in)........................................\t3.630 in.\u003cbr\u003eBore (mm)....................................92.202mm\u003cbr\u003eGasket Material............................PermaTorqueMLS\u003cbr\u003eCompressed Thickness (in).....0.036 in.\u003cbr\u003eCompressed Volume (cc)..........6.100cc\u003cbr\u003eLock Wire......................................No\u003cbr\u003eQuantity .........................................Sold individually.\u003cbr\u003eNotes..............................................Left side gasket.","brand":"Fel-Pro","offers":[{"title":"Default Title","offer_id":47079166476546,"sku":"FEL1141L","price":55.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/0618\/0354\/files\/1141l_p04_top.jpg?v=1784943053","url":"https:\/\/www.lethalperformance.com\/products\/fel-pro-fop-performance-v8-281-4-6l-permatorquemls-engine-cylinder-head-gasket-left-hand","provider":"Lethal Performance","version":"1.0","type":"link"}
