PRW INDUSTRIES INC. 4174850 PRW Industries 4174850 BBC Valve Cover Gaskets for Big Block Chevy 396-454, Rubber-Coated Steel, Pair

PRW Industries part number 4174850 valve cover gaskets are designed for Big Block Chevy engines in the 396-454 cubic-inch family. This matched pair provides a dependable sealing interface between compatible valve covers and cylinder heads, helping contain engine oil and reduce the risk of seepage around the valve cover perimeter. The gaskets are suited for replacement applications where consistent fit and durable sealing performance are required.
The construction combines a steel core with a black rubber coating for a resilient, conformable seal. This design helps the gasket adapt to mating surfaces while maintaining support around the entire valve cover perimeter. The rubber-coated steel material is well suited to the operating environment of a performance or replacement engine, offering a practical balance of strength, flexibility, and resistance to common engine fluids. The black finish also provides a clean, understated appearance when installed beneath the valve covers.
Each package includes two gaskets for servicing both sides of a compatible Big Block Chevy engine. Before installation, inspect the valve covers and cylinder head sealing surfaces for damage, distortion, or debris, and verify that the covers match the intended 396-454 application. Use the installation procedure recommended for the engine and valve cover combination, including the appropriate fastener tightening sequence and torque specifications. PRW Industries 4174850 is a direct replacement-style gasket set for enthusiasts, builders, and technicians seeking a reliable perimeter seal for compatible BBC valve cover assemblies.
