Stock rocker arm girdles

Any one seen a set? I’m thinking of having these made . Need to make sure they still fit under stock valve covers first. So how much interest is there?

 

I ran a set years ago. Used with stock and roller rockers. Don't think they fit under stock covers. I used kb valve covers.

 

Yea they don’t fit stock covers without spacers. I was going to try my rollers also
