Head Torque Specs

[captinmo]

I am in the middle of the PI head swap. I have searched the forum a using a couple of different search criteria and am not getting exactly what I want. Auto Zone's torque specs state:

1) Torque, in sequence, to 31 ft/lbs
2) Turn an additional 85 to 95 degrees in sequence
3) loosen all bolts
4) Torque, in sequence, to 31 ft/lbs
5) Turn an additional 85 to 95 degrees in sequence
5) Turn again an additional 85 to 90 degress in sequence

Does this sound right to everyone? Just want to make sure before I throw the cam covers on. Thanks!

For factory hardware yes. For APR no torque to 65ftlbs.

Okay, thanks! These are not ARP so I will go forward based on these specs. This forum has been a ton of help during my PI swap. I appreciate it a lot!!!

Yeah the reason behind that is the head bolts are Torque To Yield (TTY) and should only be used once
