Selling later A body headers Found manifolds locally

I have a NICE set off of my 66 Dart GT - factory 273 manifolds - had them on a 340 in there... they were just coated with Eastwoods Stailness paint and haven't been reinstalled - building a 360 for my 66 GT // - So these Headers fit in your 65 GT with no problems or interference anywhere ? starter , oil filter etc ?? what brand headers are they ?
