Ford 2.3L C/6 1.590in Exhaust Valves

The Ford 2.3L C/6 1.590in Exhaust Valves by Ferrea represent a critical upgrade for anyone rebuilding or performance-tuning a 2.3-liter Ford engine platform. Whether you're restoring a classic 2.3L to factory specifications or pushing toward higher RPM capability, these precision exhaust valves are engineered to replace worn or damaged originals with superior durability and thermal resistance. Ferrea has earned respect among engine builders and mechanics for manufacturing valves that outlast stock components and support aggressive ignition timing and fuel mapping.

Constructed from premium stainless steel alloy, the 1.590-inch head diameter on these exhaust valves provides optimal flow characteristics while managing extreme combustion temperatures that can exceed 1,400°F under load. The C/6 designation refers to Ferrea's stem diameter and head geometry configuration, which ensures precise fitment in your Ford 2.3L cylinder head without modification. The valve's seat angle and margin design work in concert with your cylinder head's port geometry to maximize scavenging efficiency and reduce backpressure—critical factors in maintaining engine longevity and supporting reliable power output across the RPM band.

These valves suit full engine rebuilds, high-mileage replacements, or performance upgrades on Ford 2.3L Ecoboost, Ranger, Mustang, and early Thunderbird platforms. If you're installing a new camshaft or upgrading valve springs to support higher lift and duration, upgrading to Ferrea exhaust valves eliminates the risk of stock valve failure under sustained high-RPM operation. Installation requires standard valve removal and cleaning procedures; no special tools or machine work is needed if your cylinder head is within specification. This is a per-valve sale—verify your quantity requirement based on your complete rebuild scope.
