I have begun my performance upgrades on my '97 F150, which for the time being includes a Ford Motorsports (Powerdyne) supercharger and Ford Motorsports headers. I chose these particular headers because of price compared to JBA, etc. I received them yesterday and plan to install them this weekend. How do these headers compare to JBA or other more expensive brands? The quality does not look quite like I expected. Maybe the appearance does not matter compared to their performance. Should I have bit the bullet and sprung for JBA's? Thanks for the info.
