Ok guys my timing chain recently broke and I am replacing it right now....Im frustrated with the car cuz before that the H20 pump was gonna go out (replaced it). Since my timing chain broke I heard I might have some valves bent ...Since im frustrated with my car right now so I was thinking of having someone else do it for me. Around how much would it be to replace valves on an LT1?

 

I'd say over $1000 labor, then add in parts. If you're going that far just save up some more money and port the heads and toss a cam in, or just rebuild the entire engine.
