First, thanks for all of the replies and suggestions.
Since I don't have an engine hoist, I decided to go the easy route and grind it all down and use an epoxy again. This time I used Belzona 1212 with some fiber mesh as a patch. Supposedly much better than JB Weld.
So far so good... although it doesn't look pretty but she runs and that's all that matters! If I can get another 10+ years out of it with no leaks, I'll be shocked.
