Dougs headers or TTI step headers?
I'm starting to think that with as much damage as you've had to do to those TTI headers, it's some other MAJOR issue. I'm sorry, but it looks like they sent you wrong ones, you've got the wrong motor mounts, something big.
If I was TTI I'd gladly ship you a new set just to get those pics off the net.
I've used Dougs, and could not be happier. They're tight in a couple spots but the hardware, gaskets, hell even the damn stickers were top notch. I did have a bit of trouble getting the bolts into the head but they did eventually go.
