Unfortunately, I have been unable to get valve cover castings at any reasonable price for a few years now. The foundry that was doing them for me was purchased, and then shut down, by a bigger outfit. Other foundries I have looked at can't use the existing tooling, and if I went to the expense of changing the tooling the price per casting is more than double what I paid before. I am still looking to get back into making the valve covers, but am not sure if or when I will be able to do it...
