It does not fit the 12-valve 5.9 (1989-1998, VE or P7100 mechanical pump), the common rail 5.9 (2003-2007, CP3 pump), the 6.7L ISB or QSB, the 8.3L ISC or QSC, the 8.9L ISL or QSL, or the 4BT 3.9 four-cylinder.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How do I tell which 5.9 I have?\u003c\/strong\u003e\u003cbr\u003eTwo quick checks. First, look at the valve cover: six separate small covers means the 12-valve engine (1989-1998) and this head does not fit; one full-length cover means the 24-valve engine. Second, on a 24-valve engine, look at the fuel system: if a high-pressure fuel rail runs along the head with a line to each injector, that is the common rail engine (2003-2007) and this head does not fit; if the high-pressure lines come straight from the VP44 rotary pump, that is the engine this head fits.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How do I confirm it fits my truck?\u003c\/strong\u003e\u003cbr\u003eCompare the number cast into your original head against the casting number and Replaces list above, or send us your engine serial number and CPL number and we will verify the arrangement before shipping. The 5.9 ISB was built in many ratings and CPL configurations, so the serial number is the fastest way to confirm.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How many do I need?\u003c\/strong\u003e\u003cbr\u003eOne. This is a single one-piece head that covers all six cylinders, so a complete engine takes just 1 cylinder head.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What equipment does this cylinder head fit?\u003c\/strong\u003e\u003cbr\u003eIt fits Dodge Ram 2500 and Ram 3500 pickups from 1998.5 to 2002. On the vocational side it fits medium duty trucks, school buses, step vans and Class C motorhomes built with the same non-common-rail 5.9 ISB: fits Blue Bird and Thomas Built school buses, fits Freightliner FL60 and FL70 trucks and fits International 4000 series trucks. It also fits generator sets, irrigation pumps and agricultural and construction equipment powered by this engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I reuse my original head bolts, and what do they torque to?\u003c\/strong\u003e\u003cbr\u003eUse new bolts - they are torque-to-yield and single-use. The 24-valve engine uses 6 bolts per cylinder: 44 ft-lb on all bolts, then 89 ft-lb, then a recheck at 89 ft-lb, then a final 90 degree turn on all of them. Fit a new head gasket at the same time.\u003c\/p\u003e\n\n\u003cp\u003e\u003cem\u003eThis is an aftermarket replacement part.
