326-455 Pontiac Exhaust PORT SIZE 1.53in. x 2in.

The FEL-PRO 326-455 Pontiac Exhaust PORT SIZE 1.53in. x 2in. gasket is a precision-engineered exhaust manifold gasket designed specifically for classic Pontiac V8 engines in the 326–455 cubic inch displacement range. This gasket seals the critical joint between the cylinder head and exhaust manifold, preventing exhaust gas leakage that can compromise both performance and durability.

Constructed with a multi-layer steel core and composite facings, this gasket is rated for high-temperature exposure, ensuring it can withstand the thermal cycling and pressure demands typical of exhaust systems. The 1.53-inch by 2-inch port opening matches the factory exhaust port dimensions precisely, ensuring a perfect seal without gaps that would cause exhaust leaks or backpressure loss.

Mechanics and engine builders routinely specify FEL-PRO gaskets for Pontiac restorations and hot rod projects due to their reliability and longevity. This gasket is compatible with stock manifolds and headers, making it an ideal choice for anyone looking to restore or enhance the performance of their classic Pontiac vehicle.
