Didn't strip the head, just the threads. Anyway, went to the chevy dealership in town and picked up TWO nuts, just incase we stripped another. Got it all put together, and it's up and running saweeeeeet now. Also managed to find a buyer for the wrong gears since we couldn't find the box they came in and the company refused to take them back, so that was pretty awesome too. Will put some pictures up in about 20 minutes.
