Re: Manifold Torque
I use 35 pounds and has worked well. There were some who used as high as 55 pounds. I think they were associating the size with head nuts which are working against compression. I agree that many statements in the "red' book are incorrect. Being in print makes it look official. One thing I stress is to tighten manifold nuts from the center outward and in stages. Nothing like trapping a bow and breaking the manifold to ruin your day. Of course you want the manifold to be on the same plane (flat, straight, etc.) as much as possible.
