Those are EV6 style injectors that are shorter (LS3 style). You'll probably want some aftermarket ones like these from Texas Speed:

Don't do that. Run the GM injector. There are top adapters for the height differences and there are connector adapters for the electronics. MissedMo infectors are garbage. The same injector flowing more fuel will have different characteristics.
