Construction & Design

The Cometic MLX RHS Head Gasket is constructed from multiple layers of stainless steel, incorporating an integrated stopper layer that enhances sealing around the combustion chamber. This design minimizes bore distortion, which can lead to premature gasket failure or engine damage. Both sides of the gasket are coated with Viton, a high-performance elastomer known for its excellent resistance to heat, oil, and chemicals, ensuring a durable seal under extreme operating conditions.

The gasket’s precise thickness of .049" balances the need for a tight seal with maintaining proper combustion chamber volume and compression ratio. This attention to detail in construction and materials ensures that the gasket performs reliably in the demanding environment of the Dodge Viper’s powerful 8.4L V10 engine.
