ATS H11 Headstuds?

[Big_Rubber]

Ok well I'm putting these in my truck next saturday along with the new HG, now has anyone used these before and know what we should torque them down to on the 6.7? I want to get all my ducks in a row when I replace my headgasket so were not searching for specs on all this crap

They are rated the same as ARP 625's correct? If so my 625's are torqued to 160ftlbs.

I would torque them each to a equal 85ftlbs and then move up in 15ftlbs settings until you reach 160ftlbs. Use a real good silver anti-seeze and use alot. You don't want to get any popping what so ever. You should start over if you do.

A trick that helps. Get enough plastic bottle caps to set on each stud. As you tighten one set a cap on the stud. This will help to keep you from skipping a stud or from wasting time of torquing it twice.

Once you start do not stop, Take short breaks between each round if you get tired but don't walk away for like 30 minutes or more.

Thanks Matt good info, my mechanic is actually going to be doing this one thankfully, gettin a big bottle of ARP lube. as far as being rated the same as 625's ive heard yes and no, I suppose I should call ATS... but who knows how far that will actually get me with their customer service... I just couldn't pass up the price 500$ for the set of studs

i know the h-11 material is supposed to have a higher tensile strength than the arps

[mattpopp]

H-11'a have a higher tensile strenght then A2000's but not 625's, I think they are rated the same at 260,000.

Richard Brown told me to use Silver Ant-Seeze and not the ARP lube. He was saying that the ARP lube really is not that great of stuff. But alot of people use it so take it for what it is worth.

Oh ok thanks matt

A lot of really good info on the ARP website, you just have to dig a little. There is a science to it so be informed.
