2017 ram 2500 broken manifold bolts

I'm on the 4th set of bolts on my driver side and 3rd set on my passenger side. The passenger side was warped so bad, the downpipe was about 1/2" out of position when I put it all back together.

Supposedly if you take your warped manifolds and have them machined flat, then reinstall them, it is very rare for the issue to come back. Because they don't continue to warp I guess. I've never had enough time for my truck to be out of service long enough to have them machined.

I bought a new set of manifolds and bolts and gaskets last time ($300 for everything) and plan to have my old ones machined flat for when the new ones warped and snap the bolts. The good news is I've done this enough, it's a quick job now.
