Cometic Chevy Mark-IV BB V8 .042in ArmorCore Exhaust Mani Gskt Set-Brodix Big Duke/Head Hunter Heads

When you're working on a Chevrolet Mark-IV Big Block V8, especially one fitted with Brodix Big Duke or Head Hunter heads, you need an exhaust manifold gasket that can handle the heat and pressure. This set from Cometic Gasket includes two ArmorCore exhaust manifold gaskets, specifically designed for that .042 inch thickness. They're built to create a strong seal between your exhaust manifolds and the cylinder heads, which is crucial for keeping exhaust gases contained and preventing leaks.

These gaskets use an AFM material, which is a synthetic rubber bonded to an aluminum core. This construction gives them a temperature resistance of over 250°F and an 85 percent recovery rate, meaning they can handle the expansion and contraction that happens with heat cycles without losing their sealing ability. A notable benefit of this material is that it doesn't require any gasket sealers, and you won't need to re-torque them after installation, simplifying the job. They are manufactured to meet and exceed OEM quality standards, giving you confidence in their performance.
