Well they are used macs. And i heard they are hard to line up. But they were all fine except for one on the drivers side. So i meesed with it for awhile and got the one bolt in. So i assumed the 2nd bolt would go in as well. But after its about half way in i realize its cross threaded. So i figured i already messed it up so i just tightened it all the up. Its on there good and tight. I guess im just screwed if i ever have to take them off right? Also everything else went fine on the install. Just that one damn bolt.
Cross threaded a bolt on header,how bad???

My dad has a kit that can clean up and straighten threads which would probably be good to look into if you ever need to take it off again. Pretty simple to use, if you could get to it or use it with the heads on the car.
Are these Al. heads?
You have great luck if you were able to get a cross threaded bolt tight.
The next time you pull the exhaust, plan on pulling the head as well.
You will need to drill out the damaged threads and install a helicoil.
It is easy to do, but you must have direct access to the hole. So pulling the head is necessarry.
Your favorite parts store should have the helicoil kit you need.
If they don't then its time for a new favorite parts store.
