Cometic Gaskets - 4.080 MLS Head Gasket .040 - SBF

The Cometic Gaskets 4.080 MLS Head Gasket .040 - SBF is engineered for Small Block Ford engines, offering a 4.080-inch bore and 0.040-inch compressed thickness. Constructed from multiple layers of stainless steel, it ensures superior strength, rebound ability, and corrosion resistance. The outer layers are embossed and coated with Viton, a high-temperature and chemical-resistant polymer, providing exceptional sealing performance without the need for additional sealants or re-torquing. This gasket is ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks, effectively withstanding the shearing forces between different materials. Its design promotes even torque load distribution across the sealing surface, resulting in reduced bore distortion and enhanced engine performance.
