Product Description

Serious street performance, modified oval track and bracket racing. Mid-range to 7,000 RPM.

Dart Iron Eagle Platinum 23° 215cc heads are for big cubic inch, high RPM applications which favor peak power over low end flexibility.

Long wearing Bronze valve guides, screw-in studs, multi-angle intake seats and hardened and radiused exhaust seats are standard. Best of all, our precision cast ports produce outstanding airflow without time consuming porting.

Assemblies include Stainless Steel valves, premium springs, locks, retainers, studs, guide plates and seals.

Heads are sold individually.
