FERRARI APPLICATION
Swirl Polished Performance Valves
Ideal for both competition and street applications, they
are similar in material and design to
SI's 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 Silver line
Series, use the Portflow, as they are suitable for these applications.
Quicksilvers feature increased undercut stems and thicker
margins for increased flow and performance.
