Trick Flow is at it again, Ford fans! This time Trick Flow is serving up a heaping helping of horsepower for the legendary Ford FE. Presenting the PowerPort® 175 cylinder heads—specially designed and engineered to deliver more go for 390-428 engines!
The heads are a direct bolt-on for all 1961-76 engines. They’re made from top-quality A356-T61 aluminum so they’re much lighter but still as strong as OE castings. The intake runners have been optimized to increase flow velocity, and Trick Flow’s special CNC Street Ported treatment guarantees proper dimensional accuracy and balance between the runners. Other performance improvements include bronze alloy valve guides, ductile iron valve seats, and multi-angle valve seat machining on Serdi® 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 individually.
