This car doesn't offer a 2.0. What engine do you have?

If this is a DOHC engine, then it's an interference engine and very likely has a bunch of bent valves now. I would do a complete compression test before going any further.

Unless he actually removed the head and inspected the seating of all the valves, he hasn't seen anything that could confirm that valve aren't bent. A leakdown test or complete dissassembly are the only 2 ways to know for sure.
