If that block was running and not leaking, that would weigh heavily on my decision making. Regardless of what some may "think" or "say" about the repair, if it was working, it is probably better than what "they" can do. "Ugly" doesn't always mean "bad".
I just say ugly as it doesn't even cover the whole flame deck surface. As horribly drawn below, I would worry about a pathway for cylinder combustion to cross talk.
