For sale Ported 455 exhaust manifolds. Approx 2.32" outlets (stock is 2"), and ported inlets. Mounting surface has been milled true. Pictures are of when the manifolds were first ported etc a few years ago. Manifolds have since been run, but still look very good and are ready to bolt on. They were coated with eastwood 1200 degree cast iron grey with new outlet hardware installed. Include new set of manifold bolts and shipping is included in cont us only. I originally ported these for a customer a few years ago, now I am doing a much more radical set for him, and he wants to sell these. $650
Current Pictures. I will clean them up and install the right hardware on the outlets before shipping.
Gain depends on your combo, but there are NO downsides to ported manifolds. They dont wear out and will give the combo room to grow. Yes, they will fit same as stock.
