I left it bubbling for like an hour or more do you think it is safe to hook back up?
Clean it, check that the electrolyte level in all the cells is okay (and top off if needed), and I suspect you'll be good to go. The worst case scenario is that you discover the battery isn't working, but you'll never know until you try it out or otherwise test it. If you have a hydrometer, check the specific gravity in each of the cells to make sure they're all about the same (which indicates fairly well that none are shorted). Assuming they were bubbling more or less equally, there probably isn't a completely bad cell.
An occasional modest overcharging is not a terrible thing for a battery; among other things, it makes sure all the cells are fully charged at the same time. Obviously you don't want to do this super frequently, nor overdo it.
