Torque Setting for Cobra Intake Manifold by Blue Thunder

I am installing a new Blue Thunder Intake manifold and need to know if the torque settings are the same as the original '66 Shelby manifold.

The original Shelby Installation Manual states 15 ft/lbs. except the passenger very rear bolt which stays at 8 ft./lbs. due it being unsupported. Actually, all four corners look unsupported.

Is the Blue Thunder manifold beefier on the corners than the original. Can I torque all corners to 15 ft./lbs.?

 

Thanks ZRAYR.
