    7/16 studs????? don't think so..if you have the 9/16 they are set at 55# valley middle row 145# lower 125#....use a good torque lube ...peanut butter is what we use..dave

    torque

    I'm assuming you're saying the top row is 9/16, the bottom row is 1/2 and the inners are 7/16, which is standard.

    use the peanut butter lube and torque the top row to 140, the bottom row to 120 and the inners to 45 lbs with a crows foot on a 3/8 torque wrench.

    as to what order, you'll hear ten different versions. i always torqued middle out and had good luck.

    also you need to walk them in. start at 80, torque them all down, then go to 100, then go to 120, then do the top at 140. then torque the inside last.

    always remember the inside head bolts are the first ones off and the last ones to go on.
