ok, its time for a radiator flush. there is major sludge in the internals of this radiator. Make sure the thermostat is in the correct position as well. I've seen many cars come into my shop with the thermostat inserted backwards.

Are you sure you got all the air out of the cooling system? Air pockets are very common problem when you do any work to the cooling system. An air pocket will do what you discribe.

when you overheat an engine. certain parts expand more than usual. like pistons, crankshaft and camshaft bearings. im afraid its time to overhaul the engine. inspect for cracks etc...
check the oil on the dipstick...if it looks like a milkshake...you cracked something...head or block......sorry dude for the bad news. good luck
