ARP head bolt torque settings and procedure

Can anyone please give me the arp head bolt torque settings for a CA18 as well as the tightening procedure?

As per ARP technical advice:
Torque in THREE stages: 30 ft-lbs, then 55 ft-lbs, then 80 ft-lbs (using their moly grease).
loosen and retorque THREE MORE times!
heat cycle the studs (start and run to HOT).
let the engine cool down thoroughly
check torque on studs and tighten as necessary

( 40 newton meter, then 75 nm, then to 110 nm.)
I didnt do it 3 times over like they say, but double check the final torque.

Thanks RB, if this was already done and I just want to retorque the bolts, do i follow the same route or can I just do as normal and just unlock and retorque?

If it was done right, i dont think u need to unlock and retoque, just check the final 110nm torque.
ARP also say to use their moly lube with their torque setting, and slight more torque if u use normal oil.
Std torque is 95-103nm.

Thanks RB!!

Hi Draco,

Did you replace the head gasket? What did you use and thickness?
Where is the best to find?

Thanks

the car had a cometic gasget on, I just noticed some sweating and decided to retorque the head just to be safe.

Did you retorque the head? was it "looser" ?

thanks

yes I did, I actually torqued it a bit more than specified, I can not say it was loose, but 2 or 3 bolts felt looser than the others...
