I have a set of Real Carbon Fiber Valve covers that fit Small Block Chevy for sale - $310 shipped! They are 1/2 Inch taller than stock and Will Easily Clear Billet Rocker Arms. They are Twill Woven Carbon Fiber Material and give a High Tech Look on Your Pro Touring Car. I only had these on my car for about 300 miles till I decided to go with a different set. The only thing I'd recomend is that you get a billet rail for the bottom to help seal better. You dont need it, but it would make them nicer. These are half the price of other Carbon Valve Covers.
