Performance engines often have higher compression ratios and special cam timing. They also operate at higher RPM. In addition, they may be supercharged, turbocharged or use nitrous oxide. These conditions will increase the cylinder pressure and stress on the cylinder head gasket.
Fel-Pro Performance Head Gaskets comes with Perma Torque Blue Stripe and pre-flattened wire rings in either steel or copper. price per each
Performance engines often have a higher compression ratios and special cam timing. They also operate at higher RPM. In addition, they may be supercharged, turbocharged, or use nitrous oxide. These conditions will increase the cylinder pressure and stress on the cylinder head gasket and a brutally tough environment for the head gasket. Fel-Pro Performance Head Gaskets are designed with features to help your engine accommodate these conditions.
PermaTorque® Performance Head Gaskets Fel-Pro's must popular gasket design do date.
The latest development in head gasket technology is the multi-layer steel (MLS) design. At first glance, these gaskets look like the old-style embossed steel shim gaskets, but they are radically different. A thin rubber coating is bonded to the stainless steel shim and, as required, multiple layers (up to five) of this rubber-coated steel shim are assembled into a single gasket. The high-temperature rubber coating provides excellent fluid sealability across the outer faces and between the individual layers, while also sealing minor head and block surface imperfections. MLS head gaskets provide the ultimate in torque retention and supply extra strength to support current lightweight aluminum casting designs. They are specified on most current domestic and imported engines in production.
Why is the Fel-Pro PermaTorqueMLS Design Better than the OEM Gaskets?
Traditional original equipment manufacturer (OEM) type MLS head gaskets don't easily conform to surface irregularities, and require an incredibly smooth surface finish to provide a satisfactory seal. When the castings are new and the finish is fresh, OEM-style MLS gaskets work quite well. But when the castings are old or resurfaced with a less than perfect finish, leaks result. To seal under these adverse conditions, Fel-Pro engineers have developed the exclusive PermaTorqueMLS design, engineered for the aftermarket repair environment. These newly redesigned MLS gaskets have many unique features that allow them to seal better than other MLS gaskets on the market today.
