Chevrolet Small Block Portflow Series Stainless Valves

These valves are ideal for both competition and street applications. They are similar in material and design to competition valves, but manufactured in large production runs for all of the most popular applications. Because of the fully automated (robotic) production, SEV-series valves are priced lower than racing models, yet feature the same premium quality stainless steel forgings, Chrome stems, stellite tips, and swirl-polishing. If you do not see a valve you need in the Competition or Silverline Series, use the Portflow, as they are suitable for these applications.

Call toll free to order at 1-866-700-5877 or e-mail or use the order form for questions and to check stock.


Low Cost Swirl Polished One Piece Stainless Performance Valves for Street, Track or Quality Restorations, IMCA, Bracket Cars, Boats, Etc.
