Torque spec for ARP head studs on a 340 - 12/26/08 05:25 PM
We are assembling a 340 stroker using an APR head stud set for cast iron heads. We need the torque spec for this application. The ARP site gives a generic number but nothing specific and ARP is closed for the holiday weekend. Can anyone help?
Thanks in advance. P/n for the kit is 144-4001.

the sheet that came with mine says 90 ft lbs with ARP moly lube or 130 ft lbs with 30 wt motor oil.

Maybe with ARP lube. I even contacted Edelbrock after hearing of the high torque value...they suggested the same.
