    Re: Head Studs for 6.7L Cummins

    Great idea, so I’m tracking the ARPs are studs, right?

    So looking at the engine, I should see nuts, not bolts.... so to speak?

    Awesome, thanks!

    How bad are they to install?

    Not too bad.

    Lots of videos on YouTube.

    If you are already missing the EGR cooler, it will be easier.

    You do have to notch out the rocker girdle on the rear to clear one of the studs.

    It's recommended to check valve train lash and retorque studs.

    I checked torque on mine after 1000 miles, and they hadn't moved.

    Re: Head Studs for 6.7L Cummins

    So I just went through this and ordered some today from DDP.

    I went with the 625s after reading several threads about the arp the 2000s breaking, and from all I’ve read, the 625s were one torque cycle and done.

    Also, a lot of the breakage I saw the studs were generally rusty or pitted, and the 625s are also corrosion-resistant.

    I figured for around 1100 dollars vs. 450ish, that was a cheap premium to pay compared to a future head gasket job, and if by chance 2000 did break, I’d end up never trusting it and buying the 625s anyway.

    Just my thoughts and what I ultimately decided.

    I also plan on doing an S467 swap shortly as well, though.

    Machine work ahead will cost more than the 625s with zero labor on top of that as well.

    Again just my opinion, I see tons of people on here running 2000s or h11s just fine, but I felt the additional cost was worth the additional insurance.

    Thanks,
    Jeremy
