Construction & Design

The Cometic MLS Head Gasket features a sophisticated multi-layer steel design, combining multiple embossed stainless steel layers to provide exceptional strength and flexibility. The outer layers are coated with Viton, a high-performance fluorocarbon elastomer known for its excellent heat resistance and chemical stability. This coating enhances the gasket’s ability to seal against combustion pressures and prevent leaks.

The gasket’s center layer is an uncoated stainless steel shim, allowing precise control over thickness to accommodate specific engine tolerances. This layered construction not only improves the gasket’s ability to rebound after compression but also offers superior resistance to corrosion and wear, making it ideal for the demanding environment of the Dodge 6.1L HEMI iron block engine.

Installation & Fitment

This Cometic MLS Head Gasket is designed as a direct replacement for the 2005–2010 Dodge 6.1L HEMI iron block engines, ensuring a perfect fit without the need for modifications. Its 0.080-inch compressed thickness matches OEM specifications, allowing for straightforward installation using standard procedures. The gasket’s design eliminates the need for additional sealants, reducing installation time and minimizing the risk of leaks.

For best results, ensure that the cylinder head and block surfaces are clean and flat before installation. Proper torque specifications and sequence should be followed to maintain optimal sealing performance and engine reliability.
