What does the .030 inch undersize mean for this gasket?

The .030 inch undersize specification indicates this gasket is intended for engines where the cylinder bores have been machined (honed or bored) to be slightly larger than stock. It ensures a proper seal in these modified applications.

What is the purpose of the Viton coating on the outer layers?

The Viton coating on the embossed outer layers helps create a more robust seal against the cylinder head and block surfaces. Viton is a synthetic rubber known for its resistance to heat and chemicals, which aids in maintaining a tight seal under demanding engine conditions.

Is this gasket suitable for a stock engine?

This specific gasket is listed as .030 inch undersize and for the left side. While it's a high-quality MLS gasket, it's best suited for engines that have been bored to match this specification. Always confirm your engine's bore size before ordering.

About this part

Product Details

When you're rebuilding the top end of your 2018 or 2019 Ford Mustang's 5.0L Coyote V8, getting the right head gasket is crucial. This is the left-side Multi-Layer Steel (MLS) head gasket from Cometic, specifically made for a 94.5mm bore and sized .030 inch undersize. MLS gaskets are known for their strength and ability to seal under high pressure, making them a popular choice for performance builds or when you need a reliable seal after engine work.

Cometic builds these gaskets with embossed outer layers that are coated with Viton. This coating helps create a better seal against the cylinder head and block surfaces, especially under heat and pressure. The .030 inch undersize means it's intended for engines that have been bored out slightly, ensuring a proper fit and seal in those specific applications. This gasket is designed to fit the left side of the engine.
