Nice Valve covers. I have couple sets of the same ones with SUPER/STOCK embossed in them. The only issue with these valve covers is that the manufacturer put the baffle/PVC holes directly over rocker arms so you MUST install a shield on the inside of the valve cover or you will puke oil mist directly into your twist on oil cap/baffle or into the PVC. I like these day 2 valve covers a lot but they missed the mark in that one area. GM valve covers have the hole cut directly in line with the upper and lower valve cover bolts and the GM internal baffles do a really good job.
Just an idea for the new owner, here's what I did to mine.
