These are the magnesium covers found on 84-86 'Vettes. They are driver's quality, I painted them with a high heat paint and high heat clear. The one corner has a chip out of it, it doesn't affect sealing, I just stuck that one to the back. I had these on my truck. Valve covers, pcv grommet, breather, factory oil cap(not needed), and eight stainless buttonhead bolts- $50 shipped.
