Construction & Design

The Cometic MLS head gasket features a multi-layer steel design that expertly balances strength and flexibility. Multiple layers of stainless steel provide excellent resistance to heat, pressure, and warping, while the embossed outer layers enhance the gasket’s ability to conform to surface irregularities on the cylinder head and block. This ensures a tight, leak-free seal under extreme conditions.

Both sides of the gasket are coated with Viton rubber, a heat- and chemical-resistant material that protects against oil, coolant, and combustion gases. This advanced coating helps the gasket maintain its sealing integrity through repeated thermal cycling and mechanical stress, making it a reliable choice for demanding performance engines.

Manufactured to precise tolerances, this gasket fits perfectly on the 6.1L Gen-3 Hemi’s cylinder head and block surfaces, reducing the risk of leaks and improving overall engine reliability.
