what do you guys think
i know the flange on the headers spin. the other flange that came with the headers was also the style that spun. but im not 100% sure he used those ones. but im pretty sure it also just spins on the pipe untill you bolt them both together. i do know that the pipes on both sides are flared so the flanges cant actually touch unless you bend them. these are also the gaskets that came from clifford performance with the headers. it looks like a copper gasket would hold up better though. i have been told that with headers you need to check things and make sure they stay tight. but i only put 80 miles on it since it was done.
