Trickflow 175 "PowerPort" FE Heads

Trickflow 175 "PowerPort" FE Heads

Give your Ford 390-428 more go with Trick Flow's PowerPort® 175 cylinder heads. A direct bolt-on for all 1961-76 FE engines, the heads are made from top-quality A356-T61 aluminum so they're much lighter but still as strong as OE castings. Specially optimized intake runners increase airflow velocity, and Trick Flow's extraordinary CNC Street Ported treatment guarantees proper dimensional accuracy and balance between the runners. Other performance improvements of the PowerPort175® heads include bronze alloy valve guides, ductile iron valve seats, and multi-angle valve seat machining on SerdiR equipment. Assembled cylinder heads include premium 11/32" stainless steel valves, Trick Flow by PAC Racing valve springs, 7° or 10° steel valve stem locks, and chromoly or titanium retainer options.
The heads are available fully assembled or as bare castings. Sold as a pair.
