Ferrea GM VORTEC 37mm 5.97mm 105.5mm 20 Deg S-Flo Stock Competition Plus Intake Valve - Set of 10

This set includes ten Ferrea GM Vortec Stock Competition Plus intake valves, each measuring 37mm in diameter with a 5.97mm stem and a length of 105.5mm. These valves feature a 20-degree S-Flo design, which is engineered to improve airflow into the combustion chamber. They are a popular choice for GM Vortec engines when rebuilding or upgrading the top end for better performance.

Ferrea uses high-quality materials and manufacturing processes to create these valves. The S-Flo design is a notable feature, helping to reduce valve shrouding and promote a smoother path for air entering the cylinder. This can lead to improved volumetric efficiency and overall engine performance, especially in modified engines. They are well-built to handle the demands of performance applications.
