This Power Driven Diesel Stage 2 Hot Street CNC Ported Cylinder Head is an upgraded cylinder head for your 2003-2007 Dodge Ram 5.9L Cummins and 2007.5-2018 Dodge Ram 6.7L Cummins. The 6.7L Cummins Cylinder Head was designed to supersede the 5.9L Cylinder Head. For simplicity, Power Driven Diesel only offers 6.7L Cummins Cylinder Heads due to their ability to work on both, just be sure to use the correct model year of head gasket that matches the cylinder block of your application.

Stock Cummins heads are notorious for dropping valve seats as they accumulate hard miles from heavy towing or street hot rodding. The solution is hardened and oversized valve seats that won’t drop when you’re hauling or hot rodding! Each PDD Stage 2 Hot Street ported cylinder head is upgraded with hardened and oversized press-in valve seats, then Stage 2 CNC ported for a nearly 30% increase producing 217 CFM intake flow and 229 CFM exhaust flow. Fire-ring grooves are then cut with CNC precision producing perfect 4.550" fire-ring grooves. The heads are then finished up with a multi-angle valve job, new stock sized valves, new valve guide liners, and fully assembled with locks, retainers, new valve seals, and upgraded with PDD 4.5K performance valve springs.

Many hot street trucks have been sidelined by a blown or popped freeze plug under the valve cover which immediately mixes coolant and engine oil. Power Driven Diesel uses threaded plugs in-lieu of soft/freeze plugs so you never have to worry about coolant leaks under the valve cover. The PDD CNC Ported Stage 2 Street Series Cylinder Head is recommended for up to 2000 HP and guaranteed to exceed factory specifications, giving you the performance you can count on. While these were designed for 900HP+ applications and proven up to 2000 HP, they also work great in milder street and heavy towing applications looking to maximum EGT reduction.
