I'd completely tear down the engine. I am sure that you'll find your root cause...

Yep, 24 bent valves is the definition of a cam timing problem. Perhaps your mechanic should check this again more carefully.
Even though the pistons still look useable, the impact force has been transferred to your rod bearings as well. How much damage has been done there? I suspect someone forgot to lock down the cams at TDC during the IMS retrofit and things moved. Perhaps a chain tensioner failed as well. This motor is not toast yet but someone needs to dig deeper to assess the problem and full extent of the damage.
