Did you clean the old gasket and any corrosion from the block and head?
The water pump does not pressurize the cooling system... so if you had water going into the sump THAT FAST then something major was FUBAR.
The only way I can see a significant amount of coolant being put in the sump that fast is if it went down the lifter holes or an oil return hole in the head.
Did you use head gasket locating pins/bolts or just 'eye it up'?
My guess is that you didn't clean the old gasket, or somehow pinched the new one.
