What you saying is most the time bent valves cylinder head will come out and repaired or replaced no way around it

What else could cause this to happen a timing belt service doesn't require touching these bolts. Trying to get ideas on what could have failed to cause this to happen.
Expert:  Enes replied 2 years ago.
Belt wrong Installed , belt cheaper brand used , tensioner pulley wrong adjusted , timing hub whet bolts go not re checked with service or overtourqed

Tensioner only fits one way its slotted. Timing marks all still match in time.
Expert:  Enes replied 2 years ago.
I'd hard to say what happen. For sure most the time installation wrong but I can't confirm that without looking and feeling I can only say what i see on average
