Moroso Big Block Ford 429-460 Exhaust Block Off Storage Plate - Pair

If you're building a big block Ford 429 or 460 and have removed the exhaust heat riser or crossover, you'll need to seal up those ports. This pair of exhaust block off plates from Moroso is designed specifically for that job. They cover the openings left behind when you delete the factory heat riser, preventing exhaust leaks and keeping your engine bay cleaner.

These plates are made from solid steel, giving you a strong seal for the exhaust ports. They're a straightforward solution to clean up your engine bay and ensure no exhaust gases escape from the unused passages. Installation is typically a simple bolt-on process, assuming the original heat riser components have been removed.

Keep in mind that these plates are not CARB approved, so they cannot be shipped to California. They are a practical addition for engine builds where the factory exhaust crossover is being bypassed.
