I just did my Flex recently. Actually not a bad job to do at all. It took me about 8 hours start to finish. We dont have the phaser issues like the f150 so those should be fine. Just need the chain, both large tensioners, and only the one small one located towards the front of the car up top, a new tensioner part that you pull pin and it puts pressure on the chain (brain fart), new crank pulley bolt, vct solenoid gaskets, intake gaskets, the ford sealant recommended for cover, O ring for where coolant attaches to bottom of intake and I would change water pump while in there. Its quite simple and does not require many tools at all. Just time and the cam alignment plates. Which I purchased... And a Chrysler style pulley puller that you can barrow from autozone. I was quoted 1600-1700 just in labor through the local ford dealer. All in all I think I did mine for $500 or so plus my time.
Ps. My chain was stretched bad. I used to work at the local ford dealer like 20 years ago. They had recently had a newer f150 that had 25k miles and had to have the chain replaced for being stretched.
