From the PM:

divide by 12 and theres ft lbs.

typically if the numbers are in inch lbs, its because a typical ft lb torque wrench wouldnt be accurate at those levels.

30 degrees means you must use an angle meter and turn it 30 degrees.

You tighten twice to prevent warpage and ensure even pressure. what you do is tighten from the inside out to 62 inch lbs on the first pass, then 115 on the second.

Again, ft lbs wont help you much.
