Chevy Small Block Center-Bolt Short Ball Milled Polished Aluminum Valve Covers with Extra Breather Hole for Sealing, Clearance, and Engine Bay Detail

These Chevrolet Small Block Center-Bolt valve covers are built around the details buyers search for most: fitment, valve cover height, material, finish, ventilation, and sealing. The 2⅝" profile, center-bolt mounting style, and ball milled top style with an extra breather hole help match the cover to the correct engine build and clearance requirements.

Aluminum construction with a polished finish improves durability and engine bay appearance while supporting internal baffling for oil control. Gasket and mounting hardware are not included — match these to your application so the covers seal correctly and install cleanly.

What applications are these valve covers compatible with?
These valve covers are designed for Chevrolet Small Block Gen I V8 engines equipped with center-bolt cylinder heads, including the 5.0L (305 CID) and 5.7L (350 CID) applications produced from 1987–2000.

Will these valve covers fit my engine?
These valve covers are designed for Chevrolet Small Block Gen I center-bolt cylinder heads. Verify that your engine uses the factory center-bolt valve cover mounting pattern and that your valvetrain configuration provides adequate clearance before ordering.

What do valve covers do?
Valve covers seal the top of the cylinder heads to protect the valvetrain from dirt and debris while containing engine oil and helping prevent leaks.

What material are these valve covers made from?
These valve covers are manufactured from aluminum and feature a polished finish that provides excellent corrosion resistance and a bright, show-quality appearance.

How tall are these valve covers?
These valve covers measure 2-5/8 inches tall. The slightly taller profile provides additional clearance over many factory valve covers while maintaining compatibility with most stock and mild-performance valvetrain combinations.

Are these valve covers baffled?
Yes. These valve covers feature internal baffling to help control oil movement inside the valve cover and reduce the amount of oil reaching the breather or PCV system during engine operation.

Do I need gaskets for installation?
Yes. Valve cover gaskets are required for installation and are not included with this set.

Do I need hardware for installation?
Yes. Mounting hardware is not included and must be purchased separately.

Will these valve covers help prevent oil leaks?
Yes. When installed correctly with properly matched valve cover gaskets on clean sealing surfaces, these valve covers are designed to provide a reliable seal and help prevent oil leaks.

Are these valve covers a good upgrade over stock?
Yes. These polished aluminum valve covers provide increased durability, improved heat dissipation, and a premium appearance, making them an excellent upgrade for restoration, street performance, and custom engine builds.

Can these valve covers be used in performance builds?
Yes. These valve covers are well suited for street performance, engine swaps, and custom Small Block Chevy builds. Their 2-5/8-inch profile provides additional valvetrain clearance for many mild performance applications, though clearance should be verified for engines using taller aftermarket roller rocker arms or other oversized valvetrain components.
