I saved these valve covers from the trash and spent 10 hours scraping and sandblasting, what else is there to do during covid!

I can only find the ad for it and it lists it as 65-67 yet it is part #4180, like mine.

I have only ever seen one set like these but they were red, these only had a lot of black paint.

Any info would be great. They are made in Japan and the insides have only been wiped out.
