I installed mine 2 days ago too. I ran into the exact same problem. I ended up backing the bolts out and tried to run the factory bolts back in to clean the threads. It was a little tough so I chased the threads with my tap & Die set to clean them up which did the trick. The threads are 10mm by 1.25 if anybody wants to know. I would recommend doing this because you probably already stripped your threads. You can buy just the 10mm by 1.25 tap for probably under 20 bucks. I would also buy the die to clean up your bolts. It's also a 10mm by 1.25.

Something else I noticed... the supplied (with the Cage) bolt is long enough that if you did eat a thread or 2, the new bolt is long enough to get deep enough to engage the previously unused threads in the engine. The factory install left about 3 threads on the inside (use a flashlight and you can see this).
I ate threads as Caffeinated did, and was less worried about that after I realized this. Should get you back to factory specs.
Of course, cleaning the red locker out before you try the install will likely eliminate eating threads (and you'll be smarter than me, in the process).
