Ball hone?

I’m definitely going to find a different block for my stroker. I just hate to throw this block out, but I also don’t want to attempt to fix the broken piece. I don’t think it would be a sealing issue because the hole doesn’t go into the cooling system, and there’s still 2 bolts for that side of the housing to bolt to. Only issue I see is bolting a power steering pump to it. I have a manual steering truck that it could go in so I’m just trying to find a reason to use it for something.
A BRM ball-hone is the best if You're going to just de-glaze & re-ring it, but You should get a good ridge cutter & remove whatever is there, there is a thread on ridge removing here...forget where tho'...I use a floating cutter so-called "lathe-style". Really more boring-bar style, but it is the only type I will use, & can be had new reasonably priced.
The engine isn't junk, & if there are still threads down in that hole, just clean 'em & put a correct length longer cap screw in there or a stud. If it bugs You, You can install a bolt with a very light coat of lube & JB Weld around it, then unscrew it after it sets up & run a tap thru' it to give it the correct fit. Seriously, that's a "non-critical" load fastener situation, I sure as hell wouldn't be condemning a block over it.
