What is the bore size and thickness of this head gasket?

This Cometic MLX cylinder head gasket has a bore size of 4.200 inches and a thickness of 0.040 inches. It is specifically designed for the GM LT1/LT4 Gen-V Small Block V8 engines.

What is the benefit of the HP shim technology?

The HP shim technology increases the clamping force around the combustion chamber. This helps create a stronger seal, especially important for open deck blocks, to prevent leaks and maintain engine integrity.

About this part

Product Details

This product is a Cometic MLX cylinder head gasket set, specifically sized for a 4.200 inch bore and measuring 0.040 inches thick. It's built for the GM LT1/LT4 Gen-V Small Block V8 engines found in the 2017 and 2018 Chevrolet Corvette. This gasket is crucial for maintaining a proper seal between the cylinder head and the engine block, preventing coolant and oil leaks and ensuring efficient combustion.

The design incorporates HP shim technology, which is engineered to increase the clamping force around the combustion chamber. This is particularly beneficial for open deck blocks, helping to create a more robust seal. Additionally, the embossed outer layers are coated with Viton, a material known for its resistance to heat and harsh fluids, further enhancing the gasket's durability and sealing capability under demanding conditions.
