SB Mopar Valve Covers Steel Gray

The SB Mopar Valve Covers Steel Gray by PROFORM represent a direct upgrade path for small-block Mopar engine builders seeking authentic styling with proven durability. These tall-profile valve covers deliver the classic Mopar aesthetic while addressing real-world needs: proper crankcase ventilation control, baffled internal passages that minimize oil carryover, and a design footprint compatible with tight engine compartment layouts. Whether you're restoring a vintage Dodge, Plymouth, or Chrysler muscle car or building a modern small-block Mopar street engine, these covers bridge form and function.

Manufactured from robust steel with a professional gray paint finish, the SB Mopar Valve Covers feature a 3.25-inch tall design that clears most standard intake manifolds and air cleaner assemblies. The integral baffle system separates oil mist from crankcase gases before they exit through the breather hole, reducing vapor recirculation and keeping your PCV system cleaner. The embossed Mopar logo authenticates your engine bay while the steel construction ensures consistent fitment across the pair—critical when sealing against cylinder head spark plug bosses where vacuum leaks compromise combustion efficiency and fuel economy. At 5.7 lbs for the pair, weight distribution remains negligible, making these suitable for both stock and modified engine bay applications.

Small-block Mopar enthusiasts—from 273 to 360 cubic-inch platforms—will appreciate the plug-and-play installation that requires no modification to existing cylinder head castings. The tall profile accommodates popular aftermarket intake manifolds and carburetors without fitment interference, a practical consideration often overlooked in budget alternatives. Installation pairs these covers with OEM-style gaskets and hardware; ensure your PCV hose routing maintains system pressure balance to prevent seal leakage. These covers excel in street cars, race vehicles, and show builds where both visual authenticity and operational reliability matter equally.
