Awsome Ideas. I have had so many small blocks with and with out this issue and most of the time it is like a casting was poked thru. I have allways been cautious about using the right bolt so I dont break thru. It's really a poor set up when you thing about it. Using a stud epoxyed in the hole has allways been my thought, but when you need to remove it, it can do damage or put epoxy in the water galleys. Not cool.
