Here are some SB cast aluminum valve covers that I got from Carquest a few months ago. $60 out the door, I figured that's better than all the beat up rusty stock ones (with chewed up holes) that I was running across. Haven't put them on yet, they'll go on the engine when I put Edelbrock heads on it.
And, I just remembered I saw a pic of Weiand valve covers a while ago, here it is, from user Jacksdad on moparchat.com:
These look to be the same ones but without the top of the fins machined, with the Weiand logo put in the empty rectangle and of course with some creative painting. I suspect you can do the same with the polished model of the CP Proucts valve covers (a little more expensive than the black wrinkle that I have).
If I'm not mistaken, PAW also sells these, but they are more expensive there.
Hope this is useful for someone,
Ran
