Bear in mind that the core plugs were there to let the sand out when casting complete so they are not really required.....i.e you can clean the area thoroughly using a mirror between bulkhead and block to see what you are doing, and then use JB weld to fill over the plug indentation. I did this with a similarly placed plug on the back of my Scimitar V6 engine. Since the JB weld (or similar) will sag or run off when it is a thick blob I used masking tape across the area to form a pocket into which the goo was placed.....first having primed the area with a thin smear of goo. The remainder of the core plug can now rust away inside with no further leaks.
No the plugs are not there to stop cracked blocks if the water freezes in the winter............years ago I had a block and head crack in a 12/4 Riley with all plugs remaining intact. (water left in by me so the garage could move car but they thought I had drained it!!)
