How to know if I have an exhaust leak at header? I recently installed kooks headers and the first side I tried to install bolts and hold up the header at the same time 
Well, I stripped a couple on passanger side and could only get 5 of 6 bolts in (whether stripped or not). The one bolt that I could not get in was the last rear bolt on passanger side. These are new headers with new GM exhaust manifold gaskets.
How do I know if it is sealed good enough? Reason I am asking is because I have uneven fuel trims and my passanger side is all out of wack. How do I KNOW if it is leaking?
The drivers side I had help and all 6 went in fine. I know that side is sealed fine.

1) You should hear a ticking sound.
2) You might be able to look at the header primaries and see which one(s) are leaking by telltale black streaks left on the head.
3) See if you can feel air coming out with your hand.
4) If you stripped bolts, then they are most likely leaking.

Great!!
Alright, I know there are a couple of stripped header bolts on the side where I cannot get the rear bolt it to. I'm guessing if I try to remove or loosen the stripped bolts they might break! Would it be best (since a coouple are already stripped) to just try and force the rear bolt in and if it strips(which it will) oh well?
I think if I loosen all the bolts on that side that I might be able to get the rear one in without stripping. The problem is that the other bolts might break off if I try to loosen them.
