Power Driven Stage 2 Hot Street CNC-Ported Cylinder Head for 89-98 12v Cummins

Power Driven’s 12v Cummins Stage 2 CNC-Ported Hot Street 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. These heads receive Power Driven’s hot street port job, enlarged pushrod holes for better clearance and improved oil drainback, and threaded freeze plugs for reliable operation at high rpm. In addition, every CNC-ported Power Driven cylinder head is machined for compatibility with Power Driven’s Doweled Batwing Rocker Pedestals. After porting, valve and seat work is performed to optimize overall port flow and ensure optimal valve sealing. This head is then assembled by Power Driven’s expert technicians with OEM top-hat-style seals and street conical valve springs.

This head is available in 2 options:

• The “O-Ringed” option is O-ringed to provide the ultimate seal possible with an OEM-style head gasket.

• The “Fire-Ringed” option is machined for fire rings to provide the ultimate seal possible with a fire-ring head gasket.

The Power Driven hot street port is a moderate CNC port job that creates balanced flow across all 6 cylinders while providing large flow gains with OEM-sized valves. On Power Driven’s SuperFlow 1020 test bench, this port produced a 48% increase on the intake and a 46% increase on the exhaust. This port flows an incredible 195 CFM on the intake and 203 CFM on the exhaust at 28".

In real-world back-to-back dyno testing on an 800 hp street truck, the higher flow from this hot street port showed a 75 hp gain versus the baseline stock head. Although a bigger-than-stock camshaft is not required, this port really shines when combined with an aftermarket camshaft with larger-than-stock duration and lift. If your goal is a 1,000-hp street-driven Cummins, this is the head for you!
