308 Cylinder Heads Aluminum & Cast Iron

I have several cylinder heads I would like to sell. Three are aluminum and three are cast iron. I don't know what they are worth and I don't want to rip anybody off. If I can help out club members that need them that would be best as I am only looking for a fair price. Maybe someone can answer two questions for me. One of the aluminum heads has H145 on it,and one cast iron head has 500 on it. Can you tell me what is different about them and does it affect their value?

Thanks,
Chuck
I think that I have attatched the pictures, but we are new at this. If it doesn't work, I will do it again.
