1) Use the Irontite cleaner and sealant...follow the directions. The leak should seep coolant at first and then as the Irontite works its magic, it will stop seeping. You will need to run the engine to heat activate the sealant.
2) Re-clean the cracked area beyond the repair area and apply a coating of slow set JB Weld over and beyond the repair area. Let it set up overnight and then file and sand the repaired area to blend the repair edges to the cast iron. Apply paint and the repair should blend in and not be noticeable. Slow set holds much better than JB-Kwik.
I agree with the comments about Metal Stitching...but to make the best of where you are the fore-mentioned is a solution.
Good Luck!

Good Day!
So far this sounds like a good plan.
