Fel-Pro Performance PermaTorque MLS head gaskets are proven to handle big power any way you can make it. They're designed to maintain contact pressure between the cylinder head and block during the dynamics of engine operation. PermaTorque gaskets can seal combustion, oil, and coolant despite extreme horizontal and vertical motion between the cylinder head and block. Engines with open deck surfaces, numerous cooling passages, and relatively few head fasteners will greatly benefit from Fel-Pro performance PermaTorque MLS head gaskets. For replacement or upgrade, order the model recommended for your specific vehicle and engine application.
