Other than using the stock shorty headers which are getting pricey at over $600 a set on eBay try Crite's headers. As far as the 2x4 goes check eBay. DSC also sells them complete but over $1600 complete. There is a guy on ebay selling carbs for a great price for the 2x4 sorry don't know who though. It came up on another forum. www.dscmotorsport.com check here for some priceing and part ideas. Keep checking the classifieds here and clulb cobra and fordfe.com to shop for deals. You can find some good ones but it takes a little time sometimes. G.
