70 Dart S6 to 383BB conversion - Cast Iron Manifolds

They will work but you will do some grinding on the manifolds or steering column, bearing area, they are not just a bolt it...
Thank you, HemiSSDart. I have heard of milling the manifold to head surface a few thousands to "tilt" the driver side in toward the engine a bit. Was hoping not to have to do too much grinding or milling work. Thanks again!
