What does Multi-Layer Steel (MLS) mean for these gaskets?

Multi-Layer Steel construction means the gasket is built from several layers of steel. This design helps it maintain its shape and seal effectively under high cylinder pressures and temperatures, resisting blowouts and corrosion.

Do I need to use any sealant with these gaskets?

No, these Cometic MLS exhaust manifold 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 is the port size on these gaskets?

This specific gasket set features ports measuring 1.450 inches by 1.480 inches. This size is intended to match common exhaust manifold port dimensions for GM Gen 1 Small Block V8 engines.
