The SBC R/M 1.600in Exhaust Valves from Manley are precision-engineered components designed for small-block Chevrolet engines pursuing serious performance gains. These valves are ideal for various applications, including street cruisers, weekend track cars, and high-RPM competition engines, providing a critical interface between the combustion chamber and exhaust port.
Constructed from premium stainless steel, these exhaust valves feature optimized stem geometry that reduces friction and enhances durability compared to traditional cast-iron factory valves. The 1.600-inch head diameter is specifically engineered to maximize flow capacity while maintaining structural integrity under extreme conditions, making them a reliable choice for performance applications.
Engine builders upgrading to performance cylinder heads, roller rocker systems, and high-lift cam profiles on small-block Chevrolet platforms, including 350, 327, and 383 applications, will find these valves essential. Proper installation requires valve seat machining and spring rate validation to ensure optimal operation with the complete valve train.
