CEL...white smoke, car running very rough

I'm picking up a loaner on Saturday and will likely have it for 30 days. I'm going to look up the part number to ensure they use the updated head bolts.
1) N 000000 005754 (quantity 4)
2) A 156 016 07 69 (quantity 20)
Is this correct? Thanks!

I have 11 months of CPO warranty remaining and face a tough decision. Keep the car or sell it. My thoughts on the issue change by the day.

The fact that mine has shown no signs or symptoms of the inevitable failure, which from what I've read can come at any time, offers me no solace but instead has put me in the group of those owners who need to decide which of the Hobson choices to now make. Sigh.
