Not sure this is worth posting, but…
Somewhat before I was born, I think mid-1960’s, my father bought this Ford that had a long crack and chunk missing from the left side of the block. He rebuilt the engine and glued a piece of steel in the hole with some sort of two part epoxy. In the late 1970’s it started to weep coolant. I was tasked with removing the coolant, wire brushing as needed, and prepping to re-coat with JB Weld. The point was to make it functional and if it looked good or looked like crap was irrelevant.

If you zoom in on the below pic, you can see the left side of the block under the filter bowl looks kind of melted. That’s a large quantity of epoxy. The hole was big and the crack was bigger so it took a lot of epoxy. Doesn’t look good, but as of November 2022 when we gave it to a fellow who had a use for it, it hadn’t leaked again and it ran just fine.

First attempt at repair with epoxy lasted about 15 years +/-. Follow up with JB Weld lasted about 45 years +/- and still counting so far as I know.
No telling how many hours my father put on that thing with the epoxy repaired block. I’m confident I put well over 1000 hours on it myself, many of them would be considered abuse by many here as it was used as a skidder quite a bit. Yes, we got rid of it. Didn’t think I would ever part with it but after my father passed I couldn’t stand looking at it every time I went to the shed. Why isn’t relevant. Next to last time I drove it was on this trailer under its own power. Last time I drove it was off the trailer at its new home. It was running as good as ever and not leaking.

Point being, those who suggest epoxying a patch aren’t suggesting some half-a$$ repair that won’t last. Just something to consider. If it doesn’t work you’re out the cost of some JB Weld so it’s pretty low risk.
Braze it. Weld it. Do whatever you want. Hope it works out for you whatever you do.
Edit: BTW, for anyone actually looking at the photos, I’m aware the hood says Ferguson. It’s off a 35 (I think). Expertly fitted with a sledge hammer. It’s a junkyard hodge podge of a machine. Mostly a 9N, though.
