Bought these yesterday , ended up with two sets.. No brand name anywhere. Are they aluminum, one needs repair at mounting holes.
Just the average aftermarket valve covers produced in the 70s. I bought a new set from the local speedshop in 1982.
Ansen made them for all sorts of companies with different labels on them. I have the same set with just a chevy emblem.
I got a pair of those from J.C. Whitney back in the mid-70's. They came with a "Chevrolet" sticker that you could place on the center of the valve cover. It came off soon after.
I agree with Black Panther and ev88f, a boatload of them were sold with Mr. Gasket stickers on them as well. The BB version was used by Joel Rosen with Motion badges on them. Also ,they were made with Wieand cast in the space.
