Ok so here are a few common KNOWN failure points:
Throttle body shaft/screws
Valve damage from spinning too high with stock valve springs
So if you upgrade the throttle body and valvetrain, what's next?

Just to be sure, you're saying was a stock engine that had the factory harmonic damper installed, right?
I think I'm going to at least check the valve lash on my VVT head. I set all the valves to exactly minimum spec when I built it, it's got 700 miles and a lot of 8 to 8,800 pulls on it, so I'm curious to see if it tightened up after that abuse.

If you have to change any of the shims, aim for the maximum tolerance this time. My engine went from all intake valves at .009 and all were under that, one of which was .004. But thats a motor thats built and spent a lot of time above the stock redline. Jury is still out on my bearing wear, motor is still new enough that blackstone couldnt say conclusively if the motor was in the final stages of break in or if it was wearing quickly. When I do my next analysis in June it'll be more conclusive.
