Header bolts stripped

Sometimes the bolts aren't long enough and only catch the first 4-5 threads and pull them out. I had that happen once on a 360 and I ran a thread tap in to clean things up and found some studs long enough to make use of all the threads available in the heads. Problem solved. Made it easier to hang the headers too.

BTW: if you do take the heads off and heli-coil them make sure and seal them with high temp sealer or them may leak.
