For sale is a vintage pair of Headers for Big Block Chevrolet vehicles. I believe these to be Hedman "Hedders" Headers, and the parts book shows these as CH19, four tube headers for 1965-1967 V8 Chevrolet models Corvette, Chevelle and more.  The book says this is for models without AC, due to no provision made for smog air induction.  These are rare and near impossible to find day 2 parts, would be great for a motion restoration.  These are unrestored, original and one has a partial sticker still on the tube.   Pictures show the exact items you will receive.
