I bought a 03 zo6 243 casting cylinder head but how can i tell that this heads came from zo6 engine ? I know the zo6 valves are magnesium filled or something like that, how can i tell if the valves are magnesium filled ????

I believe your correct, I didn't want to take a valve out to identify it its sodium filled or not because i don't have a valve tool to do it. I will look at the bottom head of the valve & see if there is a part number stamped in it.
