Chrysler Big Block Short Bolt Fabricated Aluminum Valve Covers Polished for Sealing, Clearance, and Engine Bay Detail

These Chrysler / Mopar Big Block 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 polished finish improves durability and engine bay appearance while supporting 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.

What applications are these valve covers compatible with?
These valve covers are designed for Chrysler Big Block B/RB V8 engines, including B-series 361, 383, and 400 CID engines, and RB-series 413, 426 Wedge, and 440 CID engines. They are not compatible with the 426 HEMI, which uses a different cylinder head and valve cover design.

Will these valve covers fit my engine?
These valve covers are designed for Chrysler/Mopar B and RB Big Block V8 engines. Verify that your cylinder heads use the standard B/RB valve cover bolt 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 fabricated aluminum, providing excellent strength, reduced weight, and improved heat dissipation compared to factory stamped steel valve covers.

What finish do these valve covers have?
These valve covers feature a polished finish that provides a bright, show-quality appearance and enhanced corrosion resistance.

How tall are these valve covers?
These valve covers feature a tall-profile design that provides additional clearance for many aftermarket roller rocker arms, shaft rocker systems, 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 fabricated aluminum valve covers provide increased durability, additional valvetrain clearance, and a premium polished appearance, making them an excellent upgrade for restoration, street performance, racing, and custom engine builds.

Can these valve covers clear aftermarket rocker arms?
Yes. The tall-profile design provides additional clearance for many aftermarket roller rocker arms, shaft rocker systems, and other performance valvetrain components. Verify clearance for your specific rocker arm and valvetrain combination before installation.

Can these valve covers be used in performance builds?
Yes. These valve covers are ideal for street performance, racing, engine swaps, and custom Chrysler Big Block builds where additional valvetrain clearance, reduced weight, and durable fabricated aluminum construction are desired.
