1.600 R/M Exhaust Valves 5/16 5.040 AOL

The 1.600 R/M Exhaust Valves 5/16 5.040 AOL from MANLEY are precision-engineered components designed for high-performance and racing engine builds where cylinder head flow optimization is essential. These valves cater to both enthusiasts and professional builders who require reliability during sustained high RPM operation, making them ideal for competition engines and naturally aspirated stroker builds.

With a 1.600-inch head diameter and a 5/16-inch stem diameter, these valves are designed to balance flow capacity with structural integrity. The 5.040-inch all-over length (AOL) is crucial for proper seating in valve guides, ensuring correct installed height, which directly affects valve timing accuracy. The valves are manufactured to high standards, ensuring consistent performance across extended dyno runs and track sessions.

These exhaust valves are particularly suited for small-block and mid-displacement engines, making them a great choice for street rods and drag racing applications. Their robust design is intended for engines operating at high RPMs, ensuring they can withstand the demands of aggressive cam profiles and high-performance setups.
