SB Ford Aluminum Valve Covers Plain With Hole

The Racing Power Co-Packaged SB Ford Aluminum Valve Covers Plain With Hole (R6171) are a matched pair of tall, baffled aluminum valve covers designed specifically for small block Ford engines. These covers feature a breather hole integration, making them compatible with custom and stock crankcase ventilation systems without requiring additional modifications or adapters.

Constructed from lightweight aluminum, this valve cover set reduces overall engine bay weight while maintaining the structural integrity needed for engine compartment vibration and thermal cycling. The tall design accommodates high-rise intake manifolds and custom engine builds where standard-height covers create clearance conflicts. Internal baffling controls oil splash and separation, reducing windage losses and keeping oil off spark plug wells—a critical consideration for carbureted engines and custom fuel injection setups where ignition system reliability depends on dry electrode conditions.

These are ideal for street rods, restoration projects, and performance small block Ford builds where engine aesthetics and functional design matter equally. The plain aluminum finish accepts polishing, powder coating, or anodizing, giving builders complete customization control over final appearance. Whether used on 289, 302, or 351W platforms, the universal small block Ford bolt pattern ensures reliable fitment across the full engine family.

At 7.36 lbs per pair, these covers are substantially lighter than cast-iron originals, a meaningful advantage in weight-sensitive builds. The breather hole design eliminates the need for external crankcase ventilation modifications, simplifying plumbing in tight engine bays.
