The heads that started it all.

Trick Flow brought the High Port cylinder heads back because of the excellent power gains their patented design offers. In true Trick Flow performance style, we've added two more fully CNC-ported versions of the High Port cylinder head. The High Port 225 heads feature 225cc intake runners and 2.080 in. intake valves for 330-plus cfm of flow (@ 0.700 in. lift), 58cc or 70cc CNC-profiled combustion chambers, and 1.600 in. exhaust valves that allow 257 cfm to exit through the 95cc exhaust runners (@ 0.700 in. lift). Other features include bronze valve guides and interlocking ductile iron intake and exhaust seats. Assembled 70cc chamber heads are available with two valve spring packages. The 1.460 in. dual valve spring package is for hydraulic roller cams and is available with 10 degree chromemoly steel or 10 degree titanium retainers. This package can support cams with valve lifts up to 0.600 in. The 1.550 in. dual valve spring package for mechanical roller cams features 10 degree titanium retainers and can handle up to 0.680 in. of valve lift. Assembled 58cc combustion chamber heads feature 1.560 in. dual valve springs and 10 degree titanium retainers. These heads are for mechanical roller cams with up to 0.700 in. valve lift. All assembled heads include 7/16 in. ARP rocker arm studs and 5/16 in. guideplates. Bare cylinder head castings are also available.
