  • Engine: 1929 Commander 6 head bolts.

    Anyone know where I can get new head bolts for a gj6 and also maybe the torque specs?

        It's a 1929-30 Commander 6. It takes 25 #177350 and 2 13X369. Check with these vendors, especially ones that specialize in pre-war parts.

        Torque values weren't in the manuals back then. Depends on grade of bolts and whether they are dry or lubed. Could be anywhere from 65 to 85 ft. lbs. You might want to consult a bolt tightening chart first. Start tightening bolts in the middle and go in a spiral pattern. Go in at least three steps increasing the torque each time.
