Cometic Ford SB 4.080 inch Bore .075 inch MLS-5 Head Gasket (w/AFR Heads)

This Cometic Multi-Layer Steel (MLS) head gasket is built for Ford SB engines, specifically designed for a 4.080 inch bore and a 0.075 inch compressed thickness, and it includes a coolant eyebrow for use with AFR heads. MLS gaskets are a solid choice for high-output engines because they are made from multiple layers of stainless steel, which gives them strength and resistance to corrosion. They also have the ability to rebound, helping to maintain a seal under demanding conditions. The outer layers of this gasket are embossed and coated with Viton, a heat-resistant rubber material that can handle harsh sealing environments and various surface finishes. The center layer is stainless steel and can be varied in thickness to meet different requirements, making these gaskets suitable for sealing aluminum heads to aluminum blocks or aluminum heads to cast iron blocks.

The Viton coating on the outer layers is designed to withstand temperatures up to 250 degrees C (482 degrees F), ensuring a reliable seal even under high heat. This construction means you don't need to use any additional sealants, simplifying the installation process. Cometic's MLS design is well-suited for engines that produce more power than stock, offering improved sealing performance compared to traditional composite gaskets. This gasket fits a wide range of Ford Windsor V8 engines and other compatible vehicles.
