Dude stay off jegs. You don't need overpriced name brand for a set of valve covers. There were a TON of used/new centerbolt covers on ebay for well under $100. Any design you like. Stamped, fabricated, chrome, black, ribbed, etc. Don't over think it and spend too much $$$!!!!
Or if you find a set of expensive name brand ones you like, then see if you can find them used on ebay, or search the part number and they may be cheaper new even. I do that all the time. Instead of spending over $35 on a belt I got the exact same brand/# belt on ebay for $14 shipped. Do some looking around, and try to stay away from the parts magazines, they over charge like a ****!
