This was a very usefull thread. Thank you OP too bad you didnt feel encouraged to show us how the longer thread bolt ended up fitting. And to the troll that didnt contribute i see why your car got stolen lol.

The 400-8013 have just a tad bit more thread than oem. They look longer but that last 1/4" is not threaded. Also the arp nuts are 10mm vs 12mm oem so that give you more space to fit a tool onto them. Only drawback is they require a socket to tighten and you can no longer use an open wrench.
