Guys, tonight I tested the head a bit. I put water on the combustion part of the chamber, then sprayed compressed air into the intake ports. There was only a few bubbles on one valve, when I got the air gun really up against it. No water was able to escape into the ports as far as I could tell. As for the exhaust side, I still have my exhaust manifold on so it was pretty easy to stuff a rag pretty tight into the gap, then put an compressed air hose in with it. When testing these, every valve (8) had some bubbles. This was under more pressure since I was trapping the air in and pushing 100 or so psi into the manifold. Again, it didn't look like any water was leaking into the ports. I think tomorrow I am going to set it on its side, fill the intake / exhaust ports with some type of fluid like brake cleaner and see if it makes its way out of the valve. Basically doing the reverse of what I did tonight, but without air. Any idea of my test tonight indicates that the valves are bent?
