I own a backdraft number 200 something car. I want to install the header/exhaust flange kit and know where that can be purchased. But before I go to all the hassle of getting it installed I thought I'd do some research to see if the other problem I have with the headers can be resolved. And that is, where the header pipes attach to the plate that attaches to the engine, the weld/fitting isn't the best. It would appear it restricts some flow. I've got the 351 Ford Racing engine in mine. Is anyone aware of a better set of headers that will work?
