I just got my obx headers and they look good, i just need to know some info, i did a search but nobody talks about the things i need to know:

1. What is the torque for the header bolts? (on engine)

2. Did anyone have trouble getting the old bolts off from the factory headers?

3. Did you have to remove any other parts to do the install? (things that get in the way)

thanx in advance!
