item: FERREA 5000 series ENGINE VALVE FOR OLDSMOBILE F5142

5000 SERIES HI PERFORMANCE VALVES

The 5000 Series Hi Performance Valves have become the alternative for performance engine builders that use our competitors “street” or “performance valve”. These valves are machined in our CNC centers allowing tight tolerances and cost effective design.

They feature a one-piece forging made from stainless steel, a special heat treatment process, hard chrome stems, and hard tip. Most applications are available in an undercut stem and dished head, while other applications are available in straight stem and flat head.
