Chevy Small Block Perimeter Bolt Circle Track Steel Valve Covers Zinc for Sealing, Clearance, and Engine Bay Detail

These Chevrolet Small Block Perimeter-Bolt valve covers are built for racing applications needing extra clearance for high-performance camshaft and rocker arm setups. The 3⅝" profile, perimeter-bolt mounting style, and smooth top style give a classic racing look while accommodating taller valvetrain components than a standard-height cover.

Steel construction with a zinc finish improves durability 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, including the 265, 267, 283, 302, 305, 307, 327, 350, and 400 CID applications equipped with perimeter-bolt cylinder heads through 1986.

Will these valve covers fit my engine?
These valve covers are designed for Chevrolet Small Block Gen I engines with perimeter-bolt cylinder heads. Verify that your cylinder heads use the standard perimeter-bolt valve cover pattern and that your valvetrain configuration provides adequate clearance before ordering. These covers may not clear stud girdles.

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 steel and feature a zinc finish that provides corrosion resistance while offering an ideal surface for painting or custom finishing.

How tall are these valve covers?
These valve covers measure 3-5/8 inches tall. The tall-profile design provides additional clearance for many aftermarket roller rocker arms and other high-performance valvetrain components.

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 tall steel valve covers provide increased valvetrain clearance, durable construction, and a corrosion-resistant zinc finish, making them an excellent upgrade for restoration, street performance, racing, and custom engine builds.

Can these valve covers be used in performance builds?
Yes. These valve covers are well suited for street performance, racing, and custom Small Block Chevy builds where additional valvetrain clearance is required. Because stud girdle clearance can vary by manufacturer and design, verify clearance for your specific valvetrain combination before installation.
