Product Description

Trick Flow Twisted Wedge Track Heat Cylinder Head with 170cc Intake Runners, 2.02/1.60 Intake/Exhaust Valves, Dual Springs and 61cc Combustion Chambers for 289, 302 and 351W Engines.

Twisted Wedge Track Heat Cylinder Heads are perfect for Ford loving bracket racers. Trick Flow's cylinder head features 170cc intake runners, 2.02 intake valves, 1.60 exhaust valves, dual springs and 61cc combustion chambers. This head is the perfect addition to your 289, 302 or 351W engine.

Twisted Wedge Track Heat cylinder heads have a few key differences from the Twisted Wedge cylinder heads. Trick Flow designed the Track Heat heads for track use only as they are not emissions legal. This head is capable of producing 600+ hp on naturally aspirated engines making them the most winning heads in NMRA racing. They dominate the field so much that the NMRA added a weight penalty for using the heads. You get all the great performance of Twisted Wedge heads plus higher rated valve springs, 10 degree machined steel super locks, and manganese bronze guides to support camshafts with up to 0.600 in of lift.

Twisted Wedge series heads are known for their twisted wedge combustion chambers and valve layout, high flow/high velocity intake runners, top quality valvetrain components and CNC-profiled combustion chambers with bowl blending (Port-to-valve seat blending). Refined runners deliver near-CNC-ported power and air flow at cast cylinder head prices. This cylinder head comes fully assembled.

Trick Flow Twisted Wedge 170 series cylinder heads are made from A356-T61 aluminum castings which have been redesigned on the exhaust side to improve strength and water jacket integrity for increased durability.

I've heard the 03 gt 2 valve is slightly different. Would this convert the 03 to 32 valve?

Asked by: heyman83
No, this would NOT work for that application.
