Cometic Ford 302/351 SVO SB 4.030 inch Bore .045 inch MLS Head Gasket

This product includes a pair of Cometic Multi-Layer Steel (MLS) head gaskets designed for Ford 302 and 351 Windsor V8 engines with a 4.030 inch bore. These gaskets are built with multiple layers of stainless steel, featuring outer layers coated with heat-resistant Viton rubber. The compressed operating thickness is 0.045 inches. They are designed to provide maximum sealing performance for high-output engines and do not require additional sealants.

MLS gaskets are a solid choice for sealing aluminum heads to either aluminum or cast iron blocks, as they can handle the shearing forces that can occur between dissimilar metals. The multiple stainless steel layers offer increased strength and the ability to rebound, while also resisting corrosion. The Viton coating on the outer layers is a high-performance elastomer that can withstand temperatures up to 482 degrees Fahrenheit, making it suitable for demanding sealing environments. The center layer is uncoated stainless steel and can be varied to achieve different gasket thicknesses.

These gaskets fit a wide range of Ford vehicles, including models like the Bronco, E-150 Econoline, and Country Squire. They are a popular choice when rebuilding or modifying these classic Ford V8s.
