66 valiant with 360 help needed.

'64-'66 273 exhaust manifolds bolt right up. The only header options are Hooker fenderwells, Doug's chassis exit, or TTI chassis exit. If you want a set of those prepare to say goodbye to one of your nads. $$$$ Dakota/Durango manifolds will fit with enough grinding on the manifolds and/or steering coupler. '67 up manifolds won't fit on the driver's side. Oddly enough '65 C body big block manifolds work great if you want to go that route, but you will need to swap in a big block to use them.
