I bought the kooks mid length headers a couple years ago and I have just now installed them on my rebuilt engine. It appeats that the flanges that bolt to the head are too thin. I bolt them down and I get exhaust leaks mid way between the bolts. I have torqued the bolts from the inside out, and I have also tried using generous amounts of copper kote gasket sealer. No luck. Major exhaust leaks. Anyone have the same problem? Anyone have a solution?
