On a 2004 Hyundai Santa fe 2.7

I had to replace the water pump and in the process of putting it back together, someone moved one or both cans. Now I cant get the timing right.
Everything is aligned up the way it's supposed to be. But still sounds 180° out

 

I thought that Hyundai used interference engines
Where the piston and valves will occupy the same space at different times
If the cams are 180 degrees out then the it is possible the valves and piston have collided
Causing damage??? That is if you tried to crank the engine??
If you turn the engine over by hand to check the timing then possible that there is little to no damage.

Good luck to you
