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.

If you are running these on the same engine; you might want to ask someone if they have the same combustion chamber volume.
