Product Details
Starting with a compressed thickness of 0.040 inches, this Multi-Layer Steel (MLS) head gasket from Cometic is built for high-output Ford Windsor V8 engines, especially when paired with AFR cylinder heads. The multiple stainless steel layers give it strength and resistance to corrosion, while the outer layers are coated with Viton, a heat-resistant rubber material rated up to 482°F, ensuring a solid seal even under demanding conditions.
These MLS gaskets are designed to work with both aluminum and cast iron blocks, and they don't require any additional sealants, making installation more straightforward. The center layer is stainless steel and can be varied in thickness, but this specific gasket is set at 0.040 inches compressed thickness, with a 4.155-inch bore diameter, making it suitable for specific Ford SB applications. This gasket is a well-built option for rebuilding or upgrading your engine's top end.
This gasket fits a wide range of Ford vehicles, including models like the Ford Bronco, F-100, and various Econoline vans, among many others. Always double-check fitment for your specific year and model.
