SBC Polished Cast-Alm. Blank Valve Cover Set

The SBC Polished Cast-Alm. Blank Valve Cover Set from KEVKO Oil Pans & Components is engineered for small block Chevy engines that demand superior crankcase ventilation and a refined appearance. This pair of tall valve covers addresses the critical need for effective evacuation fitting integration while maintaining a professional, polished finish. Builders and performance enthusiasts rely on these covers for both street and competition applications where proper oil separation and blow-by management directly impact engine longevity and cleanliness.

Each cover features a 3.75-inch tall design with internal baffle construction to optimize crankcase air flow while minimizing oil carryover into intake systems. Cast aluminum construction provides lightweight durability, while the polished finish delivers both corrosion resistance and the classic aesthetic that enhances engine compartment presentation. The integrated evacuation fitting allows seamless connection to PCV or external ventilation systems, eliminating the guesswork in routing and ensuring proper pressure regulation across the entire crankcase. This purposeful engineering means less oil consumption, reduced atmospheric emissions, and improved ring seal integrity over time.

Technicians and engine builders working on small block Chevy platforms—from carbureted street engines to modern EFI conversions—benefit from the consistent fitment and proven performance of KEVKO covers. The blank design accommodates custom applications where off-the-shelf breather or PCV connections may not suit your specific intake routing. Installation is straightforward on any SBC platform, and the pair format ensures matching aesthetics and synchronized ventilation performance. Whether refreshing a tired engine bay or building a show-quality small block, these polished covers deliver professional results and reliable crankcase management.
