BB Yenko Valve Covers

Did they have a special YENKO valve cover for the BB, I always thought they used the OE style?

As far as I know, original Yenko cars came with standard chrome valve covers with the Tonowanda sticker on the passenger side cover. Some I've seen have a Yenko tuned sticker on the driver side cover, but not sure about if the dealer did this or not. And they should be the valve covers with the drippers, so you'll see the small pock marks for the dripper welds thru the chrome.

Yenko made their own stamped tall BB valve covers in the 70s. They had no drippers or oil fill/PCV and had "Yenko" stamped on the top. To my knowledge they never came on any of the cars, it was just part of the accessory stuff they sold.

I think we still have a set if you want pictures....

Many of those Yenko valve covers were for boat application.
