Product Details
When you're rebuilding the top end of your Ford 5.4L 3-valve engine, getting the right head gasket is crucial for a solid seal. This Multi-Layer Steel (MLS) gasket from Cometic is built for the job, designed to handle the pressures of high-output engines. It's specifically made for the left side of your engine and features a 94mm bore with a compressed thickness of 0.036 inches.
Cometic uses multiple layers of stainless steel for strength and corrosion resistance, and the outer layers are coated with Viton, a heat-resistant rubber material. This construction means the gasket seals tightly without needing any extra sealants, and it works well whether you have aluminum heads with an aluminum block or aluminum heads with a cast iron block. The stainless steel center layer can be varied to achieve different thicknesses, and this particular gasket is set at 0.036 inches compressed.
This gasket fits a range of Ford and Lincoln vehicles, including models like the Ford Expedition, F-150, and Lincoln Navigator. Always refer to the manufacturer's installation instructions for proper torque sequences and procedures.
