Do these gaskets require any sealant for installation?

No, these Cometic MLS exhaust gaskets do not require any additional sealants. They are designed to create a reliable seal on their own, even with different combinations of cylinder head and exhaust manifold materials.

What does the '.030 inch' sizing mean for these gaskets?

The '.030 inch' indicates the thickness of the gasket. This specific sizing is designed to work with the factory specifications for many GM LS engines, ensuring a proper seal and fit.

What is the advantage of Multi-Layer Steel (MLS) gaskets?

MLS gaskets are well-built for high-pressure applications. They maintain their torque, resist corrosion, and are much less prone to burning through or being pushed out compared to single-layer gaskets.
