There are two GM part numbers for the newer aluminum framed intake manifold gaskets. One for pinned and unpinned.
Pinned - 89017816
Unpinned - 89017817
The difference is the pinned end seals have rubber tits that insert into small holes in the block. Which one you will need can be determined by a visual inspection, of course after the UIM and LIM are removed.
Pic below shows what is included in the gasket kit.
