Junk yard valve covers need tall ones

[BrownPSU78]

So I bent my valve covers so out of shape that they are no longer usable...Long story..So i was gonna go to the junkyard tommarow to pickup a set...what year 302 has the tallest valve covers? I have a slightly higher lift cam and require high lift valve covers. So what should i ask for them off of?

I thought only roller rockers needed tall valve covers? I could be wrong though.
