Intake Gasket Set - BBC Ret-Port 1.800 x 2.530

The Intake Gasket Set – BBC Ret-Port 1.800 x 2.530 is a factory-spec replacement manifold gasket engineered for big block Chevy engines requiring precise port matching and reliable sealing. Built by MAHLE ORIGINAL/CLEVITE, this composite gasket set addresses one of the most critical sealing points in any high-performance or street big block—the intake manifold-to-cylinder head interface. Whether you're rebuilding a 454, 427, or 402 engine, a quality intake gasket prevents coolant and oil leakage while maintaining proper combustion chamber sealing under boost, heat, and cylinder pressure.

This gasket set features a 0.12-inch composite construction designed to handle the thermal cycling and pressure loads inherent to big block Chevy applications. The rectangular port design matches the 1.800 x 2.530-inch port dimensions found on most BBC cylinder heads, ensuring dead-accurate alignment and eliminating the risk of port mismatch that can compromise flow and cause leaks. Composite gasket material provides superior reusability compared to paper alternatives and resists degradation from modern coolants, fuel additives, and extended service intervals. The included full kit contains all gaskets necessary for a complete intake manifold installation, saving time during engine assembly or rebuild.

Mechanics and engine builders working on big block Chevy street machines, race engines, or truck restorations will find this gasket set essential for any intake manifold removal or engine refresh. Installation requires only standard hand tools and a clean, flat sealing surface; torque to factory spec (typically 25–30 ft-lbs for BBC manifold bolts) ensures lasting performance. Compatible with both stock and aftermarket intake manifolds fitted to big block Chevy engines, this kit delivers the OEM quality and precision fitment that prevents expensive coolant loss and downtime in the shop or on the road.
