BB cast iron exhaust manifolds 67 Cuda

Original cast iron exhaust manifolds from a 67 383 Barracuda that I installed TTI's on and probably never use again. No cracks that I can find and the heat riser is working freely. Left one is marked 289002 and right is 2863900 with some letters ot numbers under the part number. Really hard to make out even with pencil tracer. I removed them they are the real deal. Figured I try here before auction sight. Located in Brooksville Fl. Price $500 plus the frieght. Thanks
