I’d be interested to hear the reasoning behind torquing to 85 ft lbs in two steps. The ARP instructions on the Atlantic British website say 100 ft lbs in three steps— but those are out of date (2012). The most recent (2016) revision states 70 ft lbs. Also, ARP specifies a proprietary lube, not engine oil.
Atlantic British is great, and the videos are normally awesome, but all in all I’d be very hesitant to follow the instructions in this video.
I just removed the heads from my Disco 2 and found that someone had used these. It was impossible to remove the heads without first removing the studs from the block because of how little distance there was between the head and the firewall.
I’d therefore go very light on the loctite (or not use it at all) if you plan to do this because they’ll need to be removed later.

Ok good thanks
Those arb studs are garbage
They always come loose and course so many problems. Use stretch bolts
I wonder if these stretch to accommodate the newer composite head gasket. And if so are they reusable?
No ARP torque lube needed ?
Having just gone through this – Just a suggestion – If you do this on a classic and if the engines still on the car – Don't put the studs in before you laid the heads on the block, gasket, locating on the pins – You will not be able to get the heads back on! The current updated instruction set is quite clear on this. Also would not use the locktite. Also the torques recommended are different. Read the instructions properly.
Would you recommend the head stud system over the head bolt system on a 215 v8 Buick rebuild?
