Does anyone know what the ARP head stud torque specs are for the b series engines?

 

70lbs

 

same as the stock studs...you should verify with a helms manual...

 

Its not the exact same as stock studs.

It depends on the moly lube you use

Should be 70lbs with moly lube and 83lb with oil

 

VIREN.. took the words out of my mount

i thoguht you cannot torque them down with out that arp molly lube.?? i didnt knwo you can jsut use oil?? i was stressing alot when i thoguth i almost ran out of moly lube but now i know.. hey how do you guys torque your head studs? set the wrench to say 70 then click? thats it?

 

dont ever just go straight to 70lbs and click it.. start low say 20 then 40 then 60 then 70 step it up works the best method and you will never have a head stud faile you.. unless you run some ungodly boost..


also i like to tigthen down the nuts rather than hand tight like the instructions. I learned this tip from earl and it seems to hold better just my 2cents.

 

thats what i did.. and for the hand tite instructions? dont yo have to hand tite the stud first then put the head then the nut?

 

use a two nuts method to tighten the studs to the block before you drop the head on the block...

and tighten it in 2-3 sequence...

how does that work? hey can you reuse arp's when you take off the head? say waht if you need to change the head gasket?

 

Yes, ARP's are reusable. The two nut method is just a trick to drive studs in and out. Thread two nuts together on the stud and using 2 box end wrenches, tighten them up against each other really well. Then you can drive the stud down by turning the top nut clockwise, and both nuts should move as one. This will give you a little more strength when driving the studs down so it's not just finger tightened.

 

ahh i see now thanks...

I was on the phone with ARP the other day and they told me the torque specs for the studs were 65 ft/lbs with the moly lube.

 

I torqued mine to stock specs with moly lube it is alright no leakage
