Cometic GM LT1/LT4 Gen-2 Small Block V8 .056in MLS Cylinder Head Gasket - 4.100in Bore

When you're rebuilding the top end of your GM LT1 or LT4 Gen-2 small block V8, getting the cylinder head gaskets right is crucial for a solid seal. This Cometic Multi-Layer Steel (MLS) gasket is built to handle the demands of these high-output engines, ensuring a reliable seal between your cylinder heads and block.

These MLS gaskets are constructed from multiple layers of stainless steel, which gives them increased strength and the ability to rebound, helping to resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. This design means the gasket requires no additional sealants, making installation more straightforward. They work well with both aluminum-to-aluminum and aluminum-to-cast iron block combinations, as they can withstand the shearing forces that can occur between different metals.

The center layer of stainless steel can be varied to achieve different thicknesses, and in this case, it's set to a compressed operating thickness of 0.098 inches with a 0.056-inch uncompressed thickness. This gasket fits a range of GM vehicles, including models like the Chevrolet Camaro, Corvette, and Pontiac Firebird from the mid-90s.
