About this part

Product Details

Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example. If you're working on the 4.6L 3-valve engine in your 2005-2010 Ford Mustang, or one of the other compatible Ford and Mercury vehicles, this gasket is designed to provide a strong seal for your cylinder heads.

This gasket is built with multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it resist corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This coating is important because it helps the gasket seal effectively even with different materials like aluminum heads and cast iron blocks, and it can handle the shearing forces that can occur between them. The compressed thickness of this gasket is 0.036 inches, and it features a 94mm bore, making it a direct fit for the specified 4.6L 3-valve engines.

Because it's an MLS gasket, it doesn't require any additional sealants, simplifying the installation process when you're rebuilding your top end.
