Taped all the holes off, hooked up 5hp. Shop vac to water inlet. Remove tape off of 1 hole, scratch around with a screwdriver. Afterwards I ran the magnet into each hole. Results just a tiny amount of debris cam out.
Inside of shop vac tells the story.

I've attached a piece of speedometer cable to my drill motor, turned it CCW, down thru the water openings in the block, and with the block downside up, rooted around in the block. Gravity does the rest.

So much better to have in the shop vac instead of plugging up the tubes in the top of the radiator!!!

A much easier way to do it without tools is using RUST911. Drain the cooling system and refill with rust 911. Leave it in fir 24 hours. You can drive the car with the RUST911 in it. Drain and you will notice that the clear RUST911 is now black. Repeat the procedure till it drains clear. The rust911 will dissolve all the rust from the cooling system. It even dissolves the rust flakes in the radiator. https://www.amazon.com/Rust911-16-ga...59&sr=8-1&th=1
