Ordered a set of ARP head studs for my 2012 6.7 Cummins.
Did quite bit of research before the purchase.
Since I'm not planning on an all out build I opted for the 425 set. As far as the re-torque goes I'm reading different opinions.
On a different forum someone posted that he wasn't comfortable doing the install himself so he had a shop do it.
They torqued the head studs to 135lbs instead of 125lbs and adjusted the valves and let it go without the re-torque.
No problems. I'll follow the procedure of incrementally getting to proper torque and the proper sequence of tightening the studs.
I've also read of loosening and retorquing up to 5 times. Like to get you folks opinions.
Thanks,
Mac H.
