The Trick Flow® PowerPort® 175 Cylinder Heads are engineered to significantly enhance the performance of Ford 390-428 Big Block FE engines. These assembled heads are crafted from A356-T61 aluminum, offering a lighter yet robust alternative to factory castings. The design prioritizes increased flow velocity through optimized intake runners, complemented by Trick Flow’s precise CNC Street Porting treatment for dimensional accuracy and balanced airflow. Key specifications include 70cc combustion chambers, 175cc intake runners, and 113cc exhaust runners, all CNC-machined for peak performance. The heads are equipped with 2.190 in. intake valves and 1.625 in. exhaust valves, along with premium Trick Flow by PAC Racing dual valve springs capable of handling up to 0.680 in. of valve lift. Other included components comprise bronze alloy valve guides, ductile iron valve seats with multi-angle machining, steel retainers, and 7-degree steel valve stem locks, all designed for durability and optimal engine function. These PowerPort® 175 cylinder heads serve as a direct bolt-on for all Ford FE engines manufactured between 1961 and 1977. Specifically, they are compatible with Ford Big Block FE V8 engines in displacements including 5.9L/360, 6.4L/390, 6.6L/406, 6.7L/406, 7.0L/427, and 7.0L/428.
