Cometic Gaskets C5247-040 Small-Block Chevy Head Gasket

The Cometic Gasket MLS (Multi-Layer Steel) gasket is comprised of three layers of Stainless Steel. Cometic Gasket uses Stainless steel for increased strength, its ability to rebound and corrosion resistance. The Viton coating is heat resistant to 2500C or 4820F. The center or shim layer of the gasket is comprised of an uncoated Stainless Steel layer, which can be varied to accommodate multiple thickness requirements. The MLS gasket is ideal for both aluminum heads to cast iron blocks and aluminum heads to aluminum blocks. Gasket Materials The composition of MLS will also withstand the shearing forces created by aluminum heads on cast iron blocks. No re-torque is necessary. By design, the MLS gasket promotes an even torque load across the sealing surface allowing for measurably reduced bore distortion.
