LS1 1.600 C/P Exhaust Valves 5/16 x 5.105 OAL

The FERREA LS1 1.600 C/P Exhaust Valves 5/16 x 5.105 OAL are precision-engineered replacement valves designed for LS1-platform engines requiring high-performance exhaust flow optimization. These chromium-plated valves feature a 1.600-inch head diameter and a 5/16-inch stem, making them a direct fit for stock and modified LS1 cylinder heads that demand reliable, OEM-compatible valve replacement or performance upgrades.

FERREA exhaust valves are manufactured to exacting tolerances that ensure proper seating, consistent lift geometry, and long-term durability under engine bay conditions. The 5.105-inch overall length is calibrated for LS1 applications and maintains proper valve-to-piston clearance when installed in stock or lightly modified heads. Chromium plating provides corrosion resistance and extended valve life, particularly important in street and performance builds where thermal cycling and fuel combustion byproducts create harsh operating environments. The 1.600-inch diameter optimizes flow capacity while remaining compatible with standard LS1 valve seats.

These valves are suited for LS1 engine builders, performance shops, and enthusiasts undertaking head replacement, valve seat refurbishment, or comprehensive engine rebuilds. Whether restoring an original engine to stock specification or preparing a modified LS1 for increased boost or aggressive cam profiles, accurate exhaust valve replacement is critical to sealing integrity and combustion efficiency. FERREA's reputation in the OEM and racing supply sectors reflects decades of manufacturing precision, making these valves a reliable choice for builders who prioritize quality and fitment accuracy.
