I believe its just "grind" off some of the "ribs" from the molding process on the bottom to provide clearance for the high pressure fuel pump at the back of the engine. Looks like they also drill and tap the manifold for a fitting so you can connect your brake booster up to the manifold. (The C8 is brake by wire, but I thought it still had a brake booster for backup purposes? I guess not)
