I was searching for the same thing and came accross a site called "torkspecs.com" they say 33 ft/lbs but I want to make sure myself since it is a Auminum intak.e. I hope this is help to you.

No more than 35 ft/lbs. To be very accurate with the torque, use a 3/8 drive torque wrench not a 1/2 drive. The 1/2 inch drive torque wrench is long and designed to torque bolts that are at least 1/2 inch in diameter and require at least 60 lbs of torque. The intake manifold bolts are 3/8th with a flange. If you lose a bolt be sure that you use only flanged bolts. A flange bolt is a bolt with a molded flat washer. In my experience in the trade of rebuilding engines, never use a 1/2 drive torque wrench to tighten bolts under a 1/2 inch in diameter. FYI the term (drive) is the size of the square part of the socket and socket wrench. Available in 1/4, 3/8, 1/2, 3/4 and ect.
