Do you know what the torque specs are for the A4 Olds manifold? The CSM says 40 lb., but I'm pretty sure that is for cast iron. I don't see any other specs in the manual. Being aluminum, I don't want to overtorque the manifold.

35lbs is what GM recommends for Aluminum intakes, be sure to also use hardened washers.
Ebrock states 25lbs for theirs...Lightning Rods repair service:CLICK HERE
