I'm in the same boat with GCAT911. Real low pressure at idle, less than 5 lbs and in the high teens low 20's running. I was told by Fountain this is within spec since the closed cooling motors don't require as much raw water pressure. I'm sure the reading is taken directly off of the raw water pump for my 496's.
You raw cooled guys it needs to be higher. I would imagine your H20 pressures are pulled from block pressure.

You have to be carefull when flushing the engines. I let the
engines idle then momentarilly boost the throttle and watch the pressure guages jump then fall back off due to a lack of supply water pressure in the hose. I do however idle up the engines slightly when not moving or slowly moving.
