Hello - I am new to the forum and looking for some advice. I recently got my 427 side oiler block back from the machine shop and I am wondering if someone can help me figure out where I can get a Hex driver big enough to get the screw in freeze plugs out. I wanted to replace them with some new ones and give the threads a good cleaning and inspection before I build the engine. Any help or advice is greatly appreciated. Thanks.
