Product Details
When you're rebuilding the top end of your Ford Y-Block V8, you need a head gasket that can handle the job. This Cometic Multi-Layer Steel (MLS) gasket is built specifically for that purpose, featuring a 3.860-inch bore and a .040-inch compressed thickness. It's designed to provide a reliable seal for a wide range of classic Ford vehicles, including models like the F-100, Fairlane, and Thunderbird from the 1950s and early 1960s.
What makes this gasket stand out is its construction. It's made from multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it resist corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and different surface finishes. This advanced design means you don't need to use any extra sealants, making installation more straightforward and ensuring a maximum sealing performance for high-output engines.
