New valve covers

Those look pretty cool when you paint in between the ribs.
Use the same color as your block.
Tape off the ribs on each side, then paint the ribs. Now use a stout paint remover or nail polish remover on a cotton ball to remove the paint off of the tops of the ribs.
This leaves only the paint down inside the ribs and the rest of the bare aluminum can be polished or left as is... whatever you like.
I did this with a set of vintage Edelbrocks. The polished outside, ribs, and lettering looked great, but they also looked integral to the engine by being color matched.
Just an idea.

I've got some tall (to cover roller rockers), baffled, CHEAP chrome valve covers. My GF gets jealous of my Stang if I buy anything for it. We have a "lie detector" test to see if I'm thinking of my car more than her.
