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 components tailored for serious LS engine builders and performance enthusiasts who demand reliability in high-rpm applications. These exhaust valves are designed to meet the rigorous demands of modified LS1 powerplants, making them suitable for both street performance engines and track-ready builds.

Featuring a 1.600-inch head diameter, these valves align with OEM specifications for LS1 exhaust ports, ensuring a direct fit for both stock and ported cylinder heads. Constructed from premium stainless steel with a stellite-faced seat and stem, they provide excellent heat dissipation and resistance to thermal cycling, which is crucial for high-boost, naturally aspirated, or nitrous applications where exhaust temperatures can exceed stock limits.

These valves are ideal for LS1 engine builds ranging from 5.7L street performance to turbocharged or supercharged applications, where extended valve life and thermal stability are essential. The 5/16-inch stem diameter maintains OEM compatibility, while the 5.105-inch overall length ensures proper valve train geometry and clearance in both stock and modified heads.
