Edelbrock Gaskets Exhaust Manifold/Header Chrysler 426-572 Gen II Hemi Steel Core Laminate

When you're working on a classic Chrysler Gen II Hemi engine, getting a solid seal on your exhaust manifolds or headers is crucial for performance and preventing exhaust leaks. These Edelbrock exhaust gaskets are built for that job, designed specifically for the 426 to 572 cubic inch V8s that power many iconic Mopar vehicles like the Dodge Challenger and Plymouth Barracuda.

These aren't your average gaskets. They're made from Edelbrock's EnCore HTX-900 material, which is a composite of graphite-coated fiber sheets bonded to an expanded steel core. This construction gives them high heat resistance and excellent load retention, meaning they can handle the intense temperatures and pressures of a Hemi exhaust system. The material also has a notable 50% recovery rate, which helps maintain a good seal even if your header bolts loosen up a bit over time. The port size is 1.84" x 1.74", so make sure that matches your manifold or header ports for the best flow.

Getting these installed is straightforward, as they are designed to fit right in place of your old gaskets. A good seal here means you'll keep exhaust gases flowing where they should, contributing to the engine's power and keeping the noise outside the cabin.
