Sounds like it! Hitting water can happen when you're flying blind without sonic testing, but I'm surprised an experienced port man had that problem. I sure wouldn't trust JB Weld alone to fix it. Sounds like the shop applied a suitable patch though. Cast iron heads can be opened up more than aluminum because they tolerate a thinner wall thickness, but man, it's so much easier to fix holes in aluminum.
