Torque spec for ARP head studs on a 340 #175354 12/26/08 01:25 PM 12/26/08 01:25 PM

Anonymous OP Unregistered A	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. cuda273 Last edited by cuda273; 12/26/08 01:54 PM.

I even contacted Edelbrock after hearing of the high torque value...they suggested the same. 1969 Nova 454/M21/3.31 Mild mid-11 second weekend cruiser 1994 F150 XLT Super Cab 2WD 5.0/4R70W/3.55 (Daily driver)
