lol, a 19 post long thread and basically nothing was said....

I bent all of my valves once, that was a great time. To check them, turn off all the lights and stick a small, bright flashlight into the port. You will see a ring or semi ring of light if they are bent. Another thing you can do is sit the head on its side and pour water into the ports and see if it leaks out the valve.
