Fred's right. A leak down test will show you if damage was done to a valve. Each cylinder is tested for compression and for how long it is able to hold compression. It is a better test in your case that a simple compression check. Bent valves, valves that don't seat properly, and ring sealing are all verified by this test.

I'm cheering for you and hoping that the only damage is to the lifters, studs, and rockers! I guess we will find out soon.
