Ok, thanks for the help. My manifold has a 2 bolt flange. I think the easiest option is to find a 2 bolt flange to replace it with. Ive considered the fenton style headers from Langdons, but then I have to route water lines to heat the intake, I ve never done that style of conversion before. The problem with most of the manifolds Ive seen are that people want like $200 or they are warped. $200 for a stock manifold is too much, Ive seen them at the swaps for like $30-$50. Southeastern Nationals will be in Charlotte NC in Oct. Maybe I'll just wait a couple of weeks unless I find one before that.
