Ryan, due to the limited clearance between valves and pistons you will not know if they are bend unless you check it by removing the cylinder head or performing a leak down test.

What you need to know is what motor is in this car before you make any kind of decision on damage. If the engine is a 1.8 turbo then no damage as it is considered a non interference engine under no circumstance will the valves hit the cylinder head. Even if the timing belt break the 2.0 is a different story as it is an interference engine and the valves will top of the cylinder head if the belt breaks.

by the way a leak down test is the easiest way to know without disassembling the engine.

You are incorrect the 1.8 t is a interference motor

So I guess having a bolt lodged in my timing belt and crankshaft sprocket during a take off after stopping,makes me up $@$* creek without even a boat.

For future individuals who stumble onto this thread. The 1.8t is absolutely an interference engine. Very expensive and you will have some valves bent 100% of the time usually 80-100% of the valves being damaged. Head will likely need to be replaced not rebuilt if a timing belt breaks in the 1.8t. The 2.0 petrol is also interference but people sometimes get lucky and have no damage when a timing belt breaks. Most of the time they are also damaged.
