Just installed ARP custom age 625+ studs
Wow these new ARP custom age 625+ studs are one tough studs. 125 ft. lbs used to seen like allot with my old standard ARP 2000 but torquin those bads boys down to 155 ft. lbs with all those studs doing 3 torque down's per studs is a ton of work. I'd like to think of myself as in pretty good shape but this time I'm plain wore out. What is so impressive about these studs is when you get down to about 155 ft. lbs your can really feel them just tighten down with a death grip. When doing the old ones to 125 wasn't that tuff, but 155 all around sure is allot of work
I don't think my head will be lifting anymore, very impressive material

Is 155 ft. lbs. what was specified in the ARP instructions for those studs? I looked on their web site and couldn't find the installation instructions.
So basically I learned two things. 625+ ARP material is insanely strong and you better be up for the task and now I"m 100% sure that 3-4 retorques on these 24V are the only way to go. We also put a thin layer of gasket coating/sealer on the block to insure no spillage from the coolant to oil passages. I've called tons of shops and some say Yah to retorques and some say it's not necessary.
