These manifolds are garage sale priced because they have been bolted in and returned. The left manifold has what appears to be coolant on it. These do not include gaskets or hardware, what you see is what you get.
NO WARRANTY, NO RETURNS ON GARAGE SALE ITEMS
These "rams horn" cast iron manifolds were patterned off the 1962-63 327 Corvette but are not OEM remanufactured manifolds. They feature the big 2-1/2" diameter outlets and have provisions to accept original alternator type brackets.
These headers are copies of the original headers on the 62-63 Corvettes and can be used on almost any small block application. The cast in brackets are for the water tank on the drivers side and generator bracket on the passenger side. These can be cut off and smoothed per customers preference. These are a square port configuration with 1-5/16” top to bottom and also side to side. Compare to your head port size for compatibility.
