With that last picture. Now is the time to clean, scrub, and clean some more to those hard to get places. Plastic, Tape and old newspapers will help. Sandblast (if you can), then paint the engine bay.
BTW, mark all hoses, wires, and cables. Use color tape to ID electrical, air, vacuum, etc and a short explanation on each tape/paper (wrapped in contact plastic paper). The V6 might vary from these.
Same thing goes with the engine. Good Job R00BZ.
