1969 Barracuda 340 Formula S Restoration

Bummer day!!
Just got my Cuda exhaust manifolds resurfaced today and discovered there is a crack in one of them about 1" long!!! This after paying a lot of US$$$ at Carlisle and having them ceramic coated!!!! They were painted when I bought them and I could not see any cracks.
Almost looks like someone was trying to peen the crack on the outside – can see some hammer dings.
Not sure what to do now?
