Cometic – Gen 5 LT1 / LT4 Head Gasket 4.150″ Bore With .040 Thickness

The Cometic MLS gasket is comprised of three layers of Stainless Steel. The outer layers of the gasket are embossed and coated on bothsides with a flouroelastomer rubber based material (Viton)designed to meet the demands of a variety of harsh sealingenvironments, load conditions and surface finishes. The Vitoncoating is heat resistant to 250° C or 482° F.The center or shim layer of the gasket is comprised of anuncoated Stainless Steel layer, which can be varied toaccommodate multiple thickness requirements. The MLSgasket is ideal for both aluminum heads to cast iron blocks and aluminum heads to aluminum blocks. 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 measurable reduced bore distortion.
