FAQ
Will this fit my pickup?
This set is intended for industrial/non-EGR 6.7L ISB applications. For on-road pickups with EGR, use the standard on-road head set (see HS54774-1).
Does it include head bolts or a valve cover gasket?
No—neither are included. Add quality head bolts/studs and a new valve cover gasket during reassembly for best results.
Is the head gasket MLS?
Yes, the head gasket in this set is MLS for durability under cylinder pressure and thermal cycling.
What else should I replace while I’m in there?
Common add-ons include a new MLS 54774 cylinder head gasket if you need a single gasket, and ARP 247-4202 head studs for improved clamping.
Any install tips?
Have head/block surfaces checked for flatness and finish; follow Cummins procedures for fastener torque/angle and bolt/stud lubrication.
