About this part

Product Details

This Cometic Multi-Layer Steel (MLS) head gasket is built with three layers of stainless steel, featuring an embossed design on the outer layers. These outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit, ensuring a solid seal even in demanding conditions. The center layer is uncoated stainless steel and can be varied to achieve different thicknesses, allowing for precise tuning.

MLS gaskets are ideal for sealing aluminum heads to either aluminum or cast iron blocks, as they can manage the shearing forces that arise from the different expansion rates of these materials. The multiple stainless steel layers give this gasket increased strength and the ability to rebound, while also resisting corrosion. This particular gasket has a bore size of 87.5mm and a compressed operating thickness of .036 inches, making it a well-built option for high-output K20A2, K20A3, K20Z1, and K24A1 engines.
