I changed the timing chain, phasers, tensioners, guides, and cam sensors and solenoids about 30k miles ago. Truck now has 170k miles. This past weekend engine started running so rough, it had the whole front end shaking. Threw 8 codes..1 bank..lean, bank 2 rich, timing retarded, cylinder G and F misfire, and more codes. It seems to have jumped timing pretty bad.
Question: I found a company online that sell reman engine: ADVANCED ENGINE EXCHANGE. Anyone heard of them? Price is fair. Just have to pay for labor to do the change. I plan on keeping this truck till the wheels fall off.
Any info would be appreciated.

Your symptoms are exactly what happens when the screen on the VCT solenoids breaks and jams the solenoid, preventing the computer from controlling the cam position. Remove the solenoids and inspect them carefully.

If you do have to replace the engine, what is the cost from that company and does it come with valve covers and oil pan?

I agree with VTX1800N1. I'm assuming cylinders F and G are cylinders 6 and 7, which would be on the same bank.
If it did jump time though, as long as it didn't jump too much and the pistons hit the valves, you can fix it. I don't know what brand parts you used, but a lot of people have had failures with aftermarket timing parts. Oem seems to be the way to go.
