Moroso Chevrolet Big Block Mark IV (w/Conv. Heads) Exhaust Block-Off Storage Plate - Aluminum - Pair

Moroso makes this aluminum exhaust block-off plate set specifically for Chevrolet Big Block Mark IV engines that use conventional heads. If you're working on a performance build or a restoration where you've removed the exhaust manifolds or headers and need to seal up those ports for storage or to prevent debris from entering the engine, these plates are what you'll need. They're a simple, direct way to cover the exhaust ports cleanly.

These plates are made from aluminum, which is lightweight and won't add unnecessary heft to your engine bay. They're designed to fit right onto the exhaust port locations, giving you a solid seal. Since they come as a pair, you get both sides covered with one purchase, making it a convenient solution for your project.

Keep in mind that these plates are not CARB approved and cannot be shipped to California. Always refer to your local emissions regulations before installing any engine components.
