Pontiac/Big Chief Steel Core Valve Cover Gaskets

The Pontiac/Big Chief Steel Core Valve Cover Gaskets (FEL-PRO 1634) are heavy-duty engine seals engineered for classic and performance Big Block Chevrolet applications where durability and reliability are non-negotiable. These gaskets prevent oil leakage at the valve cover interface—a critical seal that protects your engine's top end from contamination and maintains proper oil pressure circulation. Whether you're rebuilding a vintage Pontiac, restoring a muscle car, or maintaining a performance big-block platform, a quality valve cover gasket pair is essential maintenance that prevents costly internal engine damage.

This pair features FEL-PRO's proven steel core construction with a 0.250-inch thick cork and rubber laminate design that resists oil degradation, thermal cycling, and vibration better than standard gaskets alone. The steel reinforcement core prevents gasket deformation under engine bay heat and maintains a consistent seal across the valve cover flange, while the cork-rubber composite material provides the conformability needed to seal minor surface irregularities on cast iron covers. This dual-material approach delivers superior longevity compared to traditional cork-only or modern elastomer-only designs, making it the preferred choice for serious engine builders and restoration shops who prioritize OEM-quality performance.

Installation is straightforward during any valve cover removal or top-end rebuild—clean the gasket seating surface thoroughly, position the new gaskets, and torque the cover bolts to manufacturer specification. These gaskets are compatible with big-block Chevrolet engines commonly found in Pontiac muscle cars and high-performance platforms. The 8.8 x 26.2-inch profile suits standard big-block valve cover configurations, and the included pair means you have both left and right gaskets ready for installation without additional ordering.
