question on 243 heads and valves recently bought a pair of heads, one is 799 and the other 243. the 243 exhaust valves look like they have some sort of coating-tan in color- on the valve face whereas the 799 valves dont look like they have any coating but steel. also one of the exhaust valve face a small area of the 'coating' is gone.

Remember some of the 243 had sodium filled valves. Look for the 5.7 casting on the bottom of the head in the area the lifters would be under. only 243 from the 5.7 had sodium valves.
^ ONLY 243 "LS6" (found only on ZO6 vettes) heads that had the sodium filled valves, not thee same 243's found on GTO's, base Vettes etc

Verdad Gallardo ohh I forgot....no that isn't a problem with the color of the valve. If only one was a very different shade of color I would be suspicious but they are all that color you say. And remember factory non modded engines run very lean.
