Pontiac 326-455 Aluminum Finned Valve Covers

The Speedway Motors Pontiac Valve Covers bring a classic finned look and durable construction to your Pontiac V8 engine build. Designed to fit 1959–1979 Pontiac engines including 326, 350, 389, 400, 421, 428, and 455 cubic inch applications, these black or polished cast aluminum covers deliver a timeless performance appearance while also helping improve heat dissipation. Their bright polished finish adds a clean, high-impact look that works equally well on restoration projects, street machines, and custom builds.

Built from cast aluminum for strength and long-lasting reliability, these valve covers are also baffled to help control oil splash and vapor inside the valvetrain area. Each cover includes one 1.25-inch push-in breather hole for use with standard breathers or PCV valves, while the 2-3/4-inch internal height provides clearance for many aftermarket valvetrain combinations. With a perimeter bolt mounting design for secure installation and a full finned top for classic style, these valve covers are a strong choice for Pontiac enthusiasts looking to combine function and appearance in one upgrade.
