Well, I was replacing the valve seals on my 93 Z, and got almost done with the exhaust side, and found the last valve was bent. whaty would cause just one valve to bend like that? I have hardly enough money to be doing any of this anyway, and now this! I am pissed!

You are replacing valve seals? Then you do not have the heads off. I can't imagine how a stem would bend, unless you or someone previously bent it. Either way, you will have to pull the head, replace the valve and the guide, cause it will be shot also IF the car has been running with a bent valve stem.If you are driving a Chevy, everything else, is just a blur. 3.4 Carbon Footprint.

No, the heads are off, I was planning on having Ben P+P them for me, but money issues are forcing me to wait. The intake valve opposite the bent one is also slightly bent, no where near as bad as the other, but still bent.1993 Lumina Z34 - Broke Yet Again

My only guess now is that one of the lifters or springs failed at one point, leaving the valve open more than it should have been, and the valves hit each other.
If its not bent in the guide area, the guide may not be messed up. Granted it still could be if it was slightly bent at the head and still managed to seat itself from the spring pressure.Ben

If your car is an auto I doubt it has ever been taken past 6500. I don't even like running my 5 speed past 7k unless I really want to show off. But I have my rev limiter set to 7750RPM.
EDIT: I've taken my car to the limiter (7750RPM) at least once... ... maybe more than that... anyway, the valves were definately not floating.--Rob
