Product Details
These Ferrea 6000 Series intake valves are built for Chevrolet LS1 engines, featuring a 2.1-inch head diameter and a 0.3135-inch stem diameter. The 4.9-inch overall length and 12-degree valve angle are designed to work with specific cylinder head porting and valve train geometry, aiming for improved airflow into the combustion chamber. This set includes eight valves, enough for a complete V8 engine.
Constructed from high-strength stainless steel, these valves are designed to withstand the heat and pressure found in performance LS1 applications. The S-Flo (Swirl-Flo) design and radial grooves in the head are intended to promote better air-fuel mixture swirl, which can contribute to more efficient combustion. Ferrea is known for producing well-built valvetrain components, and these valves are a solid option for LS1 builds where improved breathing is a goal.
When installing these valves, ensure your cylinder heads are properly prepared and that your valve springs and retainers are matched to the valve weight and intended engine RPM range. Proper installation is key to achieving the performance benefits these valves offer.
