the exhaust valves will normally look kinda white/gray/tan, I don't know about red though. If the engine is pretty worn, sometimes the exhaust will be more of a brown color than a tan..... Intake valves should be black.

while you cant really tell untill the valves are removed for inspection, post up some pics of your combustion chambers. preferably high resolution pics.

looks like the combustion chambers show normal combustion patterns. as for the dimple in the one intake valve, two possibilities;

1: it came from the factory that way due to the head builders running out of valves, or pulling one from the wrong bin.

2: the head was rebuilt at some point in its life, and the rebuilder did the same thing; IE running out of valves or pulling one from the wrong bin.

either way its no big deal. as far as the reddish deposits, that is normal. it comes from the dye in gasoline.
