318 Magnum Dropped Valve

So very disappointed! Just about to finish my build on my 1965 Dart GT while fine tuning the engine #8 dropped a valve. The 302 heads have been completely rebuilt and I have maybe 15 minutes on the engine. What is the possibility that I also bent #8 rod, damaged the wrist pin or anything else? The valve broke right at the bottom of the keeper. I am thinking that the valve was week at that point and hopefully no other valves are the same. I am posting pics of the top of #8 cylinder and the bent valve. I am hoping to have the valve and valve keeper replaced, put it all back together and be good. What are your suggestions.
