Power Driven Diesel Cummins Stage 2 CNC Ported Street Series Cylinder Head | 2003-2018 Cummins 5.9L / 6.7L

This Power Driven Diesel CNC Ported Street Series 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 your ease and ours, PDD 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 ported street series cylinder head is upgraded with hardened and oversized press-in valve seats, then CNC ported for a nearly 30% increase that exceeds 200 CFM for both intake and exhaust flow. The heads are then finished up with a CNC valve job, new stock sized valves, new valve guide liners, and fully assembled with locks, retainers, new valve seals, and upgraded with your choice of performance valve springs.

Many hard-working tow rigs/haulers and hot-rodded 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 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 have been tested on 1000 to 2000 HP applications, they also work great in milder applications especially heavy towing applications looking to lower EGT (Exhaust Gas Temperature).
