What does the .040 inch bore size mean for my engine?

The .040 inch bore size refers to the diameter of the cylinder opening the gasket is designed to seal. It's important to match this dimension to your engine's specific bore to ensure a proper fit and seal.

What is Viton coating and why is it used on this gasket?

Viton is a high-performance synthetic rubber known for its excellent resistance to heat, oil, and fuel. Coating the gasket's outer layers with Viton helps create a more robust seal, especially in demanding engine environments where high temperatures and fluids are present.

Does this gasket come with any installation hardware?

This product is for the cylinder head gasket only. It does not include head bolts or other installation hardware, which should be sourced separately based on your engine's specific requirements.
