Button Bolt not available from GM
If working on your engine, be careful removing those button bolts around the plenum & manifold. They strip easily & GM no longer supplies replacements, but some rural dealers might still have a few.
The part number for bolts that connect plenum to manifold (the long ones that bolt in from the back) is 14081017 & they cost about $2.50. Nothing like them at Ace Hardware, which otherwise has an amazing number of automotive grade bolts & clips, cheap.

If having to swap them most change the Torx bolts to cap screws (Allen key )
The Allen key doesn't strip the head out like a mis aligned Torx bit does , the bolts are more common and generally cheaper
