Cometic Ford SB 4.030 inch Bore .027 inch MLS Head Gasket (w/AFR Heads)

This product includes a Cometic Multi-Layer Steel (MLS) head gasket designed for Ford SB engines with a 4.030 inch bore and AFR heads. These gaskets are built with multiple embossed layers of stainless steel, featuring an outer layer coated with Viton rubber. The compressed thickness is .027 inches. This type of gasket is ideal for sealing aluminum heads to both aluminum and cast iron blocks, effectively handling the shearing forces that can occur between different metals. The stainless steel construction provides increased strength and resistance to corrosion, while the Viton coating on the outer layers is heat resistant up to 482 degrees Fahrenheit, making it suitable for demanding sealing environments.

Cometic MLS head gaskets are known for providing maximum sealing performance, especially for engines that produce higher output. They are designed to be used without additional sealants, simplifying installation. The multi-layer design also allows for rebound and increased strength. This gasket is specifically made to work with AFR heads, and features a coolant eyebrow.

This head gasket fits a wide range of Ford vehicles, including models like the Ford Bronco, Ford F-100, and AC Shelby Cobra. It's a solid option when you need reliable sealing for your engine build.
