TORQUE SPECS for ARP head studs on b18c1 head onto b18b1 block ?
Like the title refers to, does anyone know the torque specs for ARP HEAD STUDS ***NOT rod bolts*** for a B18C1 head ?
PS, it's being bolted to a LS block (LSVT)
Thanks,
X2

didnt you get a spec sheet inside the stud kit box? on that sheet it tells u the torque specs

dont just use any response, call ARP and get their specs, if you like to add torque for safety dont, your studs may be torque to yield.

I am trying to remember so just use this for comparison: if you have a chiltons or haynes handy does it say 72ft/lbs??? then ARPs are like 78ft/lbs, bad memory on thi stuff, **** think flywheel was 72...uh just call them again.

When I put these suckers on my GS-R block, Dynamic Autosports told me to torque them 10ft/lbs over stock. To this day there hasn't been anything wrong for the past two years.

lucky you, doesnt mean your right, if the studs are torque to yeild, they are streched just before the point where they will not relax back anymore, ill explain it as a point just before they fracture. ofcourse if youre not running 20 lbs of boost studs really dont do anything.

I finally got thru to ARP at the number listed above and they told me:
B18C1 head studs must be torqued to the following specs:
Using ARP lube or assembly lube: 70 Ft/lbs
*or*
Using a 30W oil (no assembly lube): 80 Ft/lbs
Thanks for the help !

Why do you say that about 20 psi ?
------ because he hasnt had a problem because max cylinder presures have not compromized the yield point, stock bolts will hold 15psi or more maybe, its all about insurance. just clean out the threads to get a good torque reading and liberal amounts of lube.

ATTENTION ! ACTUNG !! Given that I don't trust people for ****... I waited an hour and called back ARP to verify the torque settings of the head studs with another person.
I was then told torque should be 65 ft/lbs not 70 as said previously (-5 ft/lbs due to an aluminum head)

Someone IM'd me with this question a coupla days ago,
"Do the torque figures change when tightening a previously used ARP head stud ?"
I spoke with ARP and was told "No, the torque specifications remain the same on a previously used head stud".
Again.. GSR studs (B series) 11mm 7/16 20 - Hand tighten to block and then 65 ft/lbs w/ arp moly lube -OR- 80 ft/lbs w/ thirty weight oil.

The funny thing is that arp's torque specs are ***. Many motors that I have built and seen built will take more like 80 pounds of torque. The trick is to torque it in a sequence. Also the torque variation will be dependent on if you use the arp oil or regular oil. I have seen too many heads lift in my day under boost or compression to allow room for error.

Now being as ARP is the manufacturer of the bolts/studs, I would tend to believe them (as I did double and triple check the info) I also was very specific to my app, I gave them the block/head codes and my intended use.

i don't think torquing the bolts so high does anything benefitial. this is especially true if you have stock sleeves. what ends up happening when you take it up that high is that the bores actually start to distort. i don't like taking it anymore than a maximum of 5 lbs/ft over stock.

haha...late reply...
Following ARP's torque specs is more for the good of the studs than anything else. The studs need to have a particular torque so they may stectch properly and not too much before permanently staying stretched.
