Cometic GM L42/L61 Gen-1/2 ECOTEC .051in MLS Cylinder Head Gasket - 89mm Bore

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed layers of stainless steel, featuring an 89mm bore and a compressed thickness of 0.036 inches. The outer layers are coated with Viton, a heat-resistant rubber material capable of withstanding temperatures up to 482 degrees Fahrenheit, making it ideal for high-output engines and compatible with both aluminum and cast iron blocks. This construction helps prevent shearing forces and corrosion, ensuring a strong seal without the need for additional sealants.

The center layer is uncoated stainless steel, allowing for variations in thickness to meet different engine requirements. This gasket is well-suited for a range of GM L42/L61 Gen-1/2 ECOTEC engines, including those found in vehicles like the Chevrolet Cavalier, Cobalt, and Saturn Ion. Its robust design is made to handle the demands of modern engines, providing reliable sealing performance.
