I agree those collars are definitely part of the assembly for torquing down. I’m sure to keep the manifold from getting crushed.

Sorry, I was trying to explain the intake bolts hitting the bottom of your tapped holes and giving you false torque reading. In other words the shoulder face of the bolt isn’t tightening against the collar and making intake squish the gasket.
