These Ex manifolds are about as good as cast iron gets for performance, pretty much the same as ramshorns and better than '54 to 56  They will fit all pass cars (although '54 through '56 will need to use the offset type clutch equalizer, the left one dumps right at the stock one). They will not fit pickups unless they are put on opposite sides with the dumps at the front of the engine.  The heater damper moves but is tight, it is included. The Left is a replacement the Right is original.  There is some pitting corrosion but all ears and studs are complete and usable. see pics.  Asking $175 shipping weight about 25 lb
