full strip down, may as well replace the bearings as well etc. I personally would change the rod, doubt that it would be bent however it has had extra stress placed on it. Maybe a good time for uprated internals.
What caused the valves to hit the pistons?

The following are all possible, with varying degrees of likelihood, but you should check everything
Bent Rod
Flatted big end shell
damage from debris to the cylinder walls / and or piston / rings
Cracked valve guides on the affected cylinders
Damaged valve collets and retainers
Cracked buckets
I have seen all these on engines that had apparently just "had a valve clip a piston"
