[QUOTE="4sdvenom, post: 16430446, member: 13315"] Your headers are fine. A single flange verses separated flanges for each primary is preferred. The picture you looked at on their site may not have been the exact headers for your car or they may have been an old file picture. If your worried about slag take a rubber mallet and tap around on the headers where welded and down each primary tube and blow them out with compressed air. FYI, a single flange per side lets them mill the face flat and will seal up better than the individual flanges that can be easily warped by tightening them to much. It also puts a more even pressure across the gasket to help prevent exhaust leaks. Although it wouldn't hurt to lay a flat edge across the face of the flange and make sure it's perfectly flat from one end to the other and from top to bottom. Ken [/QUOTE]
