I think i found my problem, bad headers? What do you think.

So, I've been doing all I can to try to get these headers to work, but the interference in the header tube and idler arm is much to great. I started doing some research online and comparing photos and I think my passenger side header is much out of whack. The header is labeled green in the photos and seems to ran much to low and not in uniform with the other 2 tubes. In the photo on summit's website things look to be much different, showing the green tube to be running parallel with the other 2 tubes (red and yellow).
Take a gander at the photos and let me know what you think.

streetdak, i'm not a expert by any means but i have to agree with you on them looking diferent. is it possible to modify headers while in the car. such as heating up with a torch and bending them. im not sure if you bought them used put maybe the person before you did something to them.

any ways good luck in finding your answer to the problem.
