What is the compressed thickness of this head gasket?

The compressed operating thickness for this Cometic MLS head gasket is 0.030 inches. This measurement is critical for ensuring proper compression ratios and valve-to-piston clearance once the cylinder heads are installed.

Do I need to use any sealant with this head gasket?

No, this Cometic MLS head gasket is designed to provide maximum sealing performance without the need for additional sealants. The embossed stainless steel layers with Viton coating create a robust seal on their own.

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

Viton is a heat-resistant rubber material that can withstand high temperatures, up to 482 degrees Fahrenheit. It's used on the outer layers of this gasket to ensure a reliable seal in demanding engine conditions and to handle the shearing forces between different metal types like aluminum and cast iron.

About this part

Product Details

What you get here is a Cometic Multi-Layer Steel (MLS) head gasket specifically made for Chrysler 361, 383, 413, and 440 cubic inch engines. This gasket is designed with a 4.350-inch bore and a compressed thickness of 0.030 inches, making it a precise fit for these B/RB series V8s. It's built to handle the demands of higher output engines, ensuring a solid seal between your cylinder head and engine block.

This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This coating helps create a superior seal, even with different materials like aluminum heads on cast iron blocks, and it means you don't need any extra sealants during installation. The center layer is also stainless steel, allowing for variations in thickness to meet specific engine needs.

This gasket fits a wide range of Chrysler, Dodge, and DeSoto vehicles from the late 1950s through the late 1970s, including models like the Chrysler New Yorker, Dodge Charger, and DeSoto Adventurer. It's a well-built component for rebuilding or maintaining your engine.
