What is the compressed thickness of this head gasket?

This Cometic MLS head gasket has a compressed operating thickness of 0.062 inches. This measurement is important for maintaining the correct compression ratio after installation.

Do I need to use any sealant with this gasket?

No, this Multi-Layer Steel (MLS) head gasket is designed to provide maximum sealing performance on its own. The Viton coating on the outer layers ensures a tight seal against the cylinder head and block without the need for additional sealants.

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

Viton is a heat-resistant synthetic rubber material that can withstand high temperatures, up to 482°F (250°C). It's used on the outer layers of this gasket to create a durable and reliable seal in the demanding environment of an engine cylinder head.

About this part

Product Details

When you're rebuilding the top end of a Chrysler B or RB V8 engine, getting the head gasket right is crucial for sealing combustion pressure and coolant. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of these classic Mopar powerplants.

Cometic uses multiple layers of stainless steel for strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that seals well against aluminum or cast iron heads and blocks without needing extra sealants. This gasket has a compressed thickness of .062 inches and a 4.350-inch bore, designed to fit a wide range of Chrysler B/RB V8 applications from the late 50s through the late 70s, like the Dodge Charger, Chrysler New Yorker, and Dodge D-series trucks.

This is a solid option for both street and performance builds where reliable sealing is a priority.
