FAQ
Is this a direct-fit head for my 1989–1998 5.9L 12V?Yes. It is built for 1989–1998 12-valve Cummins applications. Confirm your engine family and year before ordering.
What comes pre-installed on the head?The Premium Stock Plus head arrives assembled (“loaded”) with valves, springs, retainers, and seals so you can bolt it on with your chosen head gasket and fasteners.
Do I need head studs?For stock power and light towing, OE-style head bolts can suffice. For higher cylinder pressure, tuning, or frequent towing, step up to ARP head studs for clamping stability. See our recommended ARP kits above.
Is there a fire-ring version?Yes — Industrial Injection offers a separate fire-ring-grooved version for high-boost builds. Contact us if you need that configuration.
Is a core charge required?Yes. A refundable core charge applies. Return an acceptable core per program terms to receive credit.
