FED heads make more power efficiently because we synchronize three critical elements. We specialize in high performance cylinder porting for racing applications. - Teardown/Clean/Inspect. - FED’s high performance porting via 5-Axis CNC. - Intake/exhaust/chambers (some chambers don’t apply). - Pressure tested for leak detection.
Frankenstein heads are scrutinized to achieve the perfect induction system. Cylinder heads are the most critical engine component for maximum output. FED applies advanced design processes to achieve target outcomes at each phase of the induction system.
