Exh. Block Off Storage Plate Set GM Gen V LT

The Exh. Block Off Storage Plate Set GM Gen V LT from MOROSO is designed specifically for LS/LT engine builders and performance enthusiasts. This set is essential for sealing exhaust manifold or cylinder head ports when upgrading to custom headers or removing factory exhaust components. By eliminating open ports, it prevents air leaks that can reduce horsepower and cause unwanted air ingestion.

Precision-machined to match OEM port dimensions, these block-off plates bolt directly to your cylinder head without the need for extensive fabrication or custom gaskets. The design ensures a clean, air-tight seal that maintains combustion chamber integrity. Additionally, the integrated storage cavity provides a convenient place to store small fasteners, clips, or wiring harnesses, helping to keep your engine bay organized during builds.

Ideal for both street and race engine builders, this set is compatible with GM Gen V LT platforms, including L83, L86, L87, and L88 variants. It seamlessly integrates with naturally aspirated and forced-induction builds, making it a versatile choice for LS/LT swaps, custom turbo or supercharger installations, and dedicated track vehicles.
