Easiest way is to drain down your coolant about a gallon or so & remove the upper plenum
You’ll have to remove the electrical connectors from TB’s,some vacuum lines & coolant lines that pass through the throttle bodies.
Couple sensors on back of plenum & you’re ready to lift off
Take care of silicon gasket; it’s reusable & clean TB’s & upper plenum good before re-installation....probably will have oil residue built up in intake.
TB’s can be left connected to plenum...just use good Air Intake cleaner instead of carburetor cleaner.
May want to have a roll of painters tape to put across intake ports after removal- to prevent dropping anything down cylinders
That’s the easiest way I found changing them & good for inspection purposes also
