Update: Finally got the car back up and running with an engine swap, nearly 9 mos after blowing the old one overheating it. Once we got into it, the old engine was just too far gone to repair and still expect it to be reliable.

Maybe I should have sold it rather than fix it, but after looking at the prices they're going for lately it was clear I wasn't going to get a good one for any less than fixing this one. And, if I were buying another I probably would not have settled for one that didn't have significantly less mileage, which would have raised the ante considerably. Plus I'd already put a good bit of work and new parts into this one since breaching the 100K mark (it's showing about 123K now). Still, it's going to take a little while to trust it again now, but I'm sure time heals all wounds.
