2.4L internal cooling passages?

Tonight I knocked out the Welch plugs, turned the engine on it's side and flushed it with water and a wire to get the stuff out.
Now....I've been doing engines for a lot of decades....dealt with some of the most troublesome overheating marques in the business.
I thought I'd seen it all, until this.
From the driver's seat:
Core plugs flush through straight across. Good. Side drain works from core plug holes..good.
Shove the nozzle into the water pump outlet in the block (left side), and the water ONLY comes out the deck ports to the head on left side. That can't be right, think I. So flashlight, wire...and I check. Water pressure from pump goes to a closed internal "manifold" along the left side of the block, only comes out into the deck ports on left side. Then through the head, down the deck ports on the right side (and out the inlet manifold, to the thermostat, and back to the radiator) down into the right side of the block to provide water that does not circulate to the sides of the cylinders.
I did it four times to make sure I didn't have something strange in my cigar.
So...question...how does coolant circulate past the cylinders? Am I dealing with some small plugged passages in the bottom of the left hand closed internal manifold?

Somehow we need to have coolant flow in the bottom half of the block, but I can't see it.
Unless 2.4L are different, the cooling passages should be similar to a 3.4L.
NOW is the time to figure this out!
Thanks

from what I have read the 2.4 block is not in the same family as the 3.4,3.8.

And since not a whole lot of folks stateside have seen one...it is a mystery.

Honed, rings, bearings, polished crank, lapped the valves (and two new ones), seals, core plugs, gaskets, surfaced deck and head, set valve lash...been driving it a couple of months, totally different car.
Got a coolant hose that just won't tighten, so a new on is in order, slight oil leak at tach drive...but it all works, and with a new clutch, smooth....

Some of the strange but successful engineering that the Haynes Engineers did for Jaguar in the 50s. I just redid a 3.4L ( not the same ) because the new modern machine shop does not understand these engines. Another total rebuild in 500 miles. Luckily we can do and figure these out with the years we have in them, but as you witnessed, mysteries are still with us. Glad you were successful.

The real headscratcher is there is absolutely no water flow through the bottom half of the block at all. No way, no place, no ports.
Yet it works....about like a Model "T" Ford with thermosiphon and no water pump.
