Last one on the driver side. Was not going in easy, so I backed out and there are some shavings on the bolt. (I think my friend was actually the one that tightened to much) Im Frustarted and dont know what to do from here.
Can I just run a tap into the head or somthing?

All this fun and the driver side header still needs to go in!!!

 

I actually cross-threaded two bolts while installing my headers, I just sort of "forced" them in rather than pull the head and get it tapped or something.

 

Whatever you do, don't do this. I had one or two get a little cross threaded the first time i did my headers a long time ago. I just got a tap and fixed them.

 

Can I tap it while the headers are still on the car?

 

Thats the thing, my bolts were cross threaded in the passenger side, so even with the header off I couldn't fit any tools or anything to try and fix the holes, not to mention they were towards the back, so i figured rather than remove the head and bring it somewhere, i should at least try to force them in and see if it works, eventually, before i do anymore work to my car i plan to pull off the head and get it fixed, but for now it works okay.
