E-CNC 185
The E-CNC 185 cylinder heads for small-block Ford are an all new design that is CNC ported to achieve optimal air-flow for maximum horsepower and torque in high performance street and light duty racing
applications. The casting and port designs are all new and engineered for great performance. All E-CNC heads feature fully CNC'd intake ports, combustion chambers and exhaust ports for improved air-flow. These heads feature 2.02" intake and 1.57" exhaust 8mm stem valves and are equipped with conical valve springs and titanium retainers for a lightweight and durable valve train combo. These small-block Ford heads have an aggressive 18° valve angle for maximum performance and accept common intake manifolds such as Edelbrock Performer RPM and RPM II.
