Power Driven Diesel’s 12v Cummins CNC Stage 3 Race Port Cylinder Head features a new aftermarket casting that is surfaced to OEM specifications in-house using state-of-the-art equipment to ensure reliable head gasket sealing, then is machined for fire rings to provide the ultimate seal possible with a fire ring head gasket. These heads receive Power Driven Diesel’s Race Port, as well as enlarged pushrod holes for better clearance and improved oil drainback, and threaded freeze plugs for reliable operation at high rpm. After porting, valve seat work is performed to fit larger aftermarket 1.87″ intake and 1.75″ exhaust valves. In addition, every CNC-ported Power Driven Diesel Cylinder Head is machined for compatibility with our Doweled Batwing Rocker Pedestals. This head is then assembled by our expert technicians with OEM top-hat style seals and Power Driven Diesel Race Conical Valve Springs.
The Power Driven Diesel Race Port is the most extreme CNC port job that can be achieved with the factory intake shelf intact. It outflows many of the competitor’s bolt-on shelf/runner intake heads while retaining the reliable factory shelf and water cooling. On our SuperFlow 1020 test bench, this port produced a 68% increase on the intake and a 65% increase on the exhaust. This port flows an incredible 234 CFM on the intake and 232 CFM on the exhaust at 28″.
In real-world back-to-back dyno testing on a 1,500 hp race truck, the higher flow from this race port showed a 119 hp gain versus the baseline stock head. This head is designed for use with an aftermarket high-lift camshaft and is not intended for street use. While it is possible to run this head on the street, the thin port walls and heavy valve spring pressure are not ideal for longevity in a street application. If you’re looking for the ultimate water-cooled head for a dedicated 12v Cummins race engine, this is it!
