What makes Multi-Layer Steel (MLS) gaskets better for high-performance engines?

MLS gaskets are built with multiple layers of steel, which allows them to better handle extreme cylinder pressures and maintain a consistent seal. They are less prone to burning through or blowing out compared to single-layer gaskets.

Do I need to use any RTV sealant with this gasket?

No, this Cometic MLS exhaust gasket is designed to create a seal without the need for any additional sealants. The multi-layer steel construction provides the necessary sealing properties on its own.

What is the thickness of this gasket?

This specific gasket has a thickness of .064 inches. This measurement is important for ensuring proper fitment and sealing within the exhaust system.

Product Details

This Cometic Multi-Layer Steel (MLS) exhaust gasket is built with a .064 inch thickness, designed to handle the extreme cylinder pressures found in GM LT1 and LT4 Gen-2 Small Block V8 engines. MLS gaskets are known for maintaining their torque settings and resisting corrosion, meaning they won't burn through or get pushed out under stress. This makes them a solid choice for applications where reliability is key.

The multi-layer steel construction allows this gasket to work effectively with different combinations of cylinder head and exhaust manifold materials, offering a versatile sealing solution. Because it's an MLS design, no additional sealants are required, simplifying the installation process. This gasket is asbestos-free, contributing to a safer working environment.
