ironic...those are the same that i am getting, or someting very close to the similar, like, powered by ford or etc...all the old school valve covers...
One vintage type valve cover that I think looks pretty good are the Power By Ford covers that came on Ford V8 cars from the 60s-70s. And maybe some of the 80s. I just know that I always found them on old V8 Fords when I was browsing through the junkyard. I should have picked some up.
These are for an FE big block, but I know I've seen the exact same design on small block Windsors. They're usually painted bright Ford engine blue.
