LAS VEGAS, NV — Trick Flow Specialties unveiled a pair of new cylinder head designs for classic American performance applications.
Today, the company showed off its new PowerPort 175 Cylinder Heads for Ford 390-428 FE and DHC 175 Cylinder Heads for small block Chevrolet on this first day of the 2016 SEMA Show.
Trick Flow got its start helping big block Ford enthusiasts get more power from their engines, and now the Akron, OH-based company has returned to its big block roots by offering its first Ford FE cylinder heads.
The direct bolt-on heads fit 1961-76 engines and feature Trick Flow’s CNC Street Ported intake and exhaust runners. This CNC porting ensures dimensional accuracy and balance between the runners and helps the heads easily outflow the stock design.
The lightweight aluminum cylinder heads have CNC-profiled 70cc combustion chambers and include bronze alloy valve guides, ductile iron valve seats, and multi-angle valve seat machining. The assembled versions include larger 2.190-inch intake/1.625-inch exhaust valves, PAC racing valve springs, and chromoly or titanium retainer options.

“There are so many different styles of FE heads out there,” said Trick Flow engineering supervisor Cory Roth. “We went with a medium riser design because it accepts more parts. We also went with the larger valve sizes than many comparable FE heads on the market. The factory FE heads that have these same valve sizes won’t fit the 390 bore, but these do.”
According to airflow testing, these larger valves, along with bigger intake ports, help yield significant airflow gains over stock — up to 258 cfm at .500-inch lift.
Roth says customer demand led to the development of the 390-428 FE heads, as well as the DHC small block Chevy heads.
