Fel-Pro 1177 L PermaTorqueMLS Engine Cylinder Head Gasket

The PermaTorqueMLS head gasket from Fel-Pro uses a multi-layer steel construction, a smart choice for engines that see a lot of action. This gasket is built to handle the high cylinder pressures and the movement that comes with performance applications, like those found in Toyota V8 P9 NASCAR engines. It's designed to keep a reliable seal even when the engine components are made of different materials, such as aluminum heads on a cast iron block, which can expand and contract at different rates.

Fel-Pro puts strategically placed sealing beads around the combustion chamber and coolant passages. This design concentrates the clamping force right where it's needed most, helping to prevent leaks under demanding conditions. These gaskets are specifically made for the realities of engine repair, offering an updated sealing solution for engines that might not have perfectly flat sealing surfaces.

Keep in mind that this gasket is not intended for use in vehicles that are required to meet emissions standards.
