Review on High-Quality GM Genuine Parts 89017866 Intake Manifold Gasket Kit: Includes Side Intake Gaskets for Optimal Performance by Olusola Reid

They were supposed to include locating pins for proper gasket positioning, but they were not installed or included with my gaskets. I removed the pins from my old Delco 89017866 AC Gaskets and used them in this replacement. The previous ones contained these pins and I have never seen them missing before. It must have been a production error. These are likely factory seconds sold for full retail.
