About this part

Product Details

This Cometic Multi-Layer Steel (MLS) head gasket is built for GM L42 and L61 Gen-1/2 ECOTEC engines. It features an 89mm bore and is .060 inches thick, designed to provide a strong seal for high-output applications. You get the gasket itself, ready to install on a range of vehicles including models like the Chevrolet Cobalt, Pontiac Grand Am, and Saturn Ion.

The gasket is constructed from multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and different surface finishes. This construction means the gasket doesn't require any additional sealants, making installation more straightforward. It's suitable for use with both aluminum and cast iron blocks, and can handle the stresses that come from mating different metals.
