Was the new radiator core flow-rate tested before installation to insure it had proper capacity? "Vomiting" strongly suggests insufficient flow rate thru the radiator; although it was new and clean when installed the honeycomb radiators are easily plugged/restricted by debris and perhaps it clogged again from residual crap in the system. My best suggestion is to have the radiator flow-rate tested.

Can we assume that when the engine was rebuilt the block was hot-tanked thoroughly and perhaps the internal water jacket surfaces bead or sand blasted to insure complete cleanliness? It sounds like that was not done or not done adequately if on startup with a new radiator you had so much debris in the cooling system.
