What is the primary advantage of using a Multi-Layer Steel (MLS) head gasket?

MLS head gaskets, like this Cometic C5460-086, are made from multiple layers of stainless steel. This construction provides superior strength and resilience compared to traditional composite gaskets, helping to maintain a seal under high pressure and temperature conditions.

What is the function of the Viton coating on this gasket?

The Viton rubber coating on the outer layers of the gasket helps create a more effective seal against the cylinder head and block surfaces. Viton is chosen for its excellent resistance to heat and various fluids, ensuring the gasket can withstand demanding engine operating temperatures.

What specific engine families does this gasket fit?

This Cometic head gasket (C5460-086) is designed for Chrysler's B and RB V8 engine families. These are common in many classic Mopar vehicles from the late 1950s through the late 1970s.

About this part

Product Details

If you're working on a classic Chrysler B or RB V8 engine, like those found in a 1960s Dodge Charger or a 1970s Chrysler New Yorker, this Cometic Multi-Layer Steel (MLS) head gasket is a solid option for your rebuild. It's designed with a 4.350-inch bore and a .086-inch thickness, intended to provide a reliable seal between your cylinder block and heads.

This gasket is built with three to five layers of stainless steel, chosen for its strength and ability to resist corrosion and rebound under pressure. The outer layers are embossed and coated with a Viton rubber material on both sides. Viton is known for its heat resistance, handling temperatures up to 482°F (250°C), which is important for keeping a good seal in demanding engine environments. This construction helps ensure a consistent seal across various surface finishes and load conditions.

This gasket fits a wide range of Chrysler, Dodge, and DeSoto V8 applications from the late 1950s through the late 1970s. When you're putting your engine back together, a well-made head gasket like this one is crucial for proper compression and preventing coolant and oil leaks.
