Pontiac Valve Covers 326-455 Tall

The Pontiac Valve Covers 326-455 Tall by TRANS-DAPT are engineered for builders and restorers who demand authentic, period-correct appearance paired with functional engineering. These tall-profile covers fit Pontiac V8 engines ranging from 326 to 455 cubic inches, making them essential for restorations, engine swaps, and high-performance builds where original Pontiac aesthetics matter. Whether you're completing a frame-off restoration or upgrading an existing Pontiac V8, these covers provide the classic look that defines vintage American muscle without compromising engine bay functionality.

Constructed from steel and finished in durable chrome, the Pontiac Valve Covers 326-455 Tall feature internal baffle design that manages crankcase ventilation while minimizing oil carryover into the intake system. The tall profile accommodates aftermarket intake manifolds and headers without interference, a critical advantage over shallow covers when upgrading ignition or fuel systems. Breather holes are strategically positioned to work seamlessly with PCV systems, allowing proper pressure relief while maintaining a clean engine compartment presentation. Sold as a pair, these covers provide complete left and right cylinder head coverage.

Mechanics and engine builders favor tall valve covers when working with Pontiac 326, 389, 400, or 455 blocks equipped with modern or stock intake systems. Installation is straightforward—the covers bolt directly to factory valve cover bosses using existing hardware. Chrome plating resists corrosion and stands up to engine bay heat cycles, ensuring long-term appearance retention in street and show applications alike. Compatibility spans original equipment and retrofit scenarios, making these covers suitable for first-time restorers and seasoned fabricators alike.
