About this part

Product Details

If you're working on a 2006-2013 Chevrolet Corvette, this Cometic Multi-Layer Steel (MLS) head gasket is built to handle the demands of your LS7 Gen-4 Small Block V8 engine. It's designed for a 4.150-inch bore and uses aftermarket sleeves only, ensuring a precise fit for your specific application.

This 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 on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This coating is crucial for sealing effectively in harsh conditions and on various surface finishes, making it suitable for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks. The center shim layer is uncoated stainless steel, allowing for different thickness requirements.
