Header Bolt Threads In Head Stripped
Well heres the deal I'm in the process of rebuilding the motor on my car, just finished bolting on my LE2 heads. I was having a friend help with installing the header onto the head. I had the header in place and had him thread in the bolts. Now all the bolts threaded in but he didn't realize how easy the bolts were suppose to thread in so I'm assuming because the header didn't align right he forced two of the bolts in and messed up two of the threads in the head.
Now he didn't put the bolts all the way in but enough to mess up the first half of the threads I think.
Is it possible to maybe just re tap it with the head on the car? I'd really hate to rip the heads off after i just got them completely on.
Any advice would help.
Thanks.

tell him he gets to pull the head and fix the threads.
you might be able retap the threads, but its highly doubtful they would hold any useful torque. if he got the bolt half way in with it crossthreaded, the bolt holes are more than likely screwed.

You're screwed (LOL!)
You'll need to pull the head and heli-coil it. The tightness and heat that these bolts see dictates that all the threads be good. Once threads are torn up, there's no magic way to put them back.
When you're ready to try it again, use a better bolt that'll hang in there and is easier to install:

Good luck!
