AKRON, OH—Trick Flow Specialties introduces PowerPort 325 Cylinder Heads, the CNC-ported version of its PowerPort Cylinder Heads for Ford 429/460.

Based on Trick Flow's PowerPort 290 Cylinder Heads--the heads that produced 600 horsepower and 547 ft.-lbs. of torque on a 10.25:1 compression Ford 460 with aftermarket cam, intake, and valvetrain--the PowerPort 325 Cylinder Heads feature larger CNC-ported 325cc intake/145cc exhaust runners. The exhaust ports have also been raised .270" from stock for better flow, and the 80cc combustion chambers have been CNC-profiled and bowl-blended for maximum combustion.

Trick Flow PowerPort 325 cylinder heads are assembled with 2.250" intake/1.760" exhaust stainless steel valves, 1.640" dual valve springs, 7/16" studs, guideplates, titanium retainers, and locks. The heads do not have provisions for EGR or other emissions equipment.
