KS WTB Edelbrock BBC louvered valve covers

[oldwagon]

I'm looking to buy a set of these valve covers, preferably magnesium or aluminum rather than chrome, as I'm going to install a Performer intake and carb and would like to have the valve covers to match them. They need to be free of dents, cracks, nicks, and gouges, especially along gasket flange. I understand these may be hard to find, but maybe somebody can point me in the right direction.
