Cometic Ford SB 4.030 inch Bore .045 inch MLS Head Gasket (w/AFR Heads)

Cometic Gasket is a well-known name for creating dependable sealing solutions, and this Multi-Layer Steel (MLS) head gasket is a prime example. It’s built for high-output Ford SB engines, specifically designed to work with AFR heads and featuring a 4.030-inch bore with a .045-inch compressed thickness. This gasket is designed to handle the demands of performance builds, offering a strong seal without needing additional sealants.

What makes this gasket stand out is its construction. It uses multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it resist corrosion and maintain its seal under stress. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and varying surface finishes, making it suitable for sealing aluminum heads to either aluminum or cast iron blocks. The center layer is stainless steel, and its thickness can be varied to meet different sealing requirements.

This gasket fits a wide range of Ford vehicles, including models like the Ford Bronco, Ford F-100, and AC Shelby Cobra, making it a versatile choice for many Ford SB engine projects. It's a solid option when you need reliable sealing for your engine rebuild.
