Actually the bent valves are on a different head. And those valves were brand new with probably somewhere between 10 and 50 miles on them (waterpump bearing locked up after a engine rebuild, stopped the idler shaft, broke the sprocket on the end of the shaft, broke the timing chain...)
I doubt that the shims under the lower sping seats are used to compensate for worn springs becuase the head had MSS dual vavle springs. The head was used on a rally car so I doubt that anyone rallying would take the time to replace the springs with dual valve springs and then wear them out (seems like it would take a while to do) and then shim them to make up for tired springs instead of replacing the springs... But who knows, I've seen some strange stuff done to cars.
