About this part

Product Details

If you're rebuilding the top end of your 2005-2010 Ford Mustang's 4.6L 3-valve engine, a solid head gasket is crucial. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of performance engines, providing a reliable seal between the cylinder head and the block.

Cometic uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C) and works well with different block and head materials, including aluminum to aluminum or aluminum to cast iron. This construction means you don't need additional sealants, and it's designed to withstand the shearing forces that can occur between dissimilar metals.

With a compressed thickness of 0.098 inches and a bore size of 94mm, this gasket is specifically made for the 4.6L 3-valve Ford modular engine. It's a well-built component that helps ensure your engine seals properly under load.
