Chevy Small Block Short Bolt Fabricated Aluminum Valve Covers with Breather Holes Black for Sealing, Clearance, and Engine Bay Detail
These Chevrolet Small Block Perimeter-Bolt valve covers are built around the details buyers search for most: fitment, valve cover height, material, finish, ventilation, and sealing. The tall profile, perimeter-bolt mounting style, and plain top style help match the cover to the correct engine build and clearance requirements.
Fabricated Aluminum construction with a black finish improves durability and engine bay appearance while supporting breather hole provisions for crankcase ventilation, internal baffling for oil control. The gasket and hardware details should be matched to the application so the covers seal correctly and install cleanly.
Use these valve covers for street performance builds, restorations, swaps, and engine dress-up upgrades where appearance, oil control, and valvetrain clearance matter. Verify gasket style, breather/PCV layout, rocker clearance, and hood clearance before installation.
