Modified cooling system through side of block

Is anyone feeding coolant to the sides of their block through the center frost plugs ?
I have read on another forum by Sanborn about feeding the coolant to the sides of the block from the timing chain cover.
The thread on mopar chat does not have the photos anymore and I wondered if anyone could post photos of the modification ,specifically how you added the lines to the time nag chain cover.
Thanks
