Default APR studs Torque sequence for D series

Im building a d16 turbo and i cant find anyone who can agree on a torque setting for the arp studs.

Ive decided on this, 20Nm, 40Nm, 60Nm, 88Nm

total 65 lbs ft

Does this sound right? anyone?

theres a sequence to torquing the head down. If i knew how to load pics up id show you. Also you torque it in steps. Dont use newton meters. everything is in foot pounds in americaaaaa

arp studs on a d might be more than 65 lb/ft, might not. start tightening in the middle and work your way out and go back over them. work in steps

I know the sequence i meant the torque setting. If thats so how come the snap on torque wrench which im using, made in the usa has only Nm on it?

Sounds right. The stuff I read didn't include the 3rd stage, I just went 15, 30, 62 on my ARP head studs (d16y8), but the extra step should be beneficial for peace of mind.
