Engineered For Serious Pressure And Sealing Stability

The Cometic C5610-077 MLX Cylinder Head Gasket is purpose-built for the demands of the 6.4L Powerstroke engine platform, offering a precise 103mm round bore and a substantial .077-inch compressed thickness. This version features six layers of multi-layered stainless steel, giving it an advantage in strength and stability compared to traditional designs. It's equipped with a galvanized steel core and reinforced with armor-clad and graphite sealing surfaces to manage irregularities in head or block surfaces, which is especially useful for high-mileage or performance-tuned engines. The MLX configuration includes a stopper layer that increases localized sealing around the combustion chamber, helping prevent leaks even under high boost pressures. With Revision A updates, this gasket reflects Cometic’s ongoing improvements for fitment, longevity, and sealing reliability. The thicker design provides more tolerance in engines with minor warping or decking variations, reducing the chance of future failures. It’s a trusted choice for diesel builders and enthusiasts looking for advanced materials and dependable performance in demanding conditions.
