BTW, don't exceed the torque specs. Some of the holes like #7,6,3,5 on the upper intake are on little extension pieces and if over-torqued will bend and crack so don't exceed the spec.

Anyone know the torque specs of the upper and lower performance intake manifold bolts?

Upper is usually around 89 in-lbs, and lower is about 18 ft-lbs—but double-check for your specific engine. A repair manual or OEM spec sheet is your best bet.
