Cometic Chrysler SB w/318A Heads 4.125in .040in MLS-5 Head Gasket Engine Quest HDS

When you're rebuilding the top end of your Chrysler SB engine, especially with 318A heads, getting the head gasket right is crucial for sealing. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of higher output engines, ensuring a strong seal without needing extra sealants.

Cometic uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and different surface finishes, making it suitable for aluminum heads on either aluminum or cast iron blocks. This particular gasket has a compressed operating thickness of 0.040 inches and a bore size of 4.125 inches, designed to work with 318A heads and compatible with Engine Quest or Edelbrock heads.

This gasket fits a wide range of Chrysler, Dodge, and Plymouth vehicles from the mid-60s through the early 90s, including models like the Dodge D150, Chrysler Cordoba, and Plymouth Barracuda. It's a well-built component designed for reliable performance in your engine build.
