Valve Covers and Pipes question

hey guys I was am building my 47 chevy and i'm putting a 350 in it. its an older 350. I was wondering what are some really cool old valve covers. I want to make it a unique look. Something you can't just run out and buy a rare find so to speak. I thought you guys might know of some cool old vintage valve covers or have some ideas.
I'm also going to bag the car. people out there who have done this where have you run the pipes. Will it sit to low in the back to run them straight out the back? If so what is the best way to run the pipes. thanks for all the help.

 

I've got a brand new set of "Ford" script valve covers for a SBC......still in the box.

Chrome a set of old Chevrolet script valve covers.

 

I think early Chevrolet script covers, nicely detailed w/ paint would look nice.
