It is in in-lbs. It is confusing, but I looked at the rest of the chart and valve cover gaskets is below it in the same section and that is something that is tightened only in in-lbs. You want to acctually look at the dual torque numbers for the upper manifold as you should tighten the pattern in two steps at the torques given. If you are like me, you don't have a torque screwdriver or in-lb measuring device at all. you might try Auto Zone or Advance Auto as they loan out specialty tools with just a deposit. Usually I just do it by feel and end up over tightening it. But, the intake manifold is important and will cause problems if it is not done correctly. Vacuum leaks there can cause problems so I reccomend that you try to get an in-lb screwdriver or I believe they come in 1/4" wrench configurations. I believe, if I remember my math correctly, you divide by 12to get ft-lbs. So, 44in-lbs would be 3.7 ft-lbs and 101in-lbs is 8.4 ft-lbs. My torque wrench starts at 10 ft-lbs i think. You could back off it a hair and it would be close.
I am attaching the Torque spec table that shows the 2 torques to use for doing the tightening sequence once completely and then finish with the second number.
