Difficulty levels differ on installing these headers. If your vehicle has low miles and you exhaust is clean then you can expect every thing to just bolt off. However if the system is rusted be prepared to use some source of heat to remove rusted bolts. Or if your lucky the bolts will snap and then just use new ones. Have some new nuts and bolts available. I used MAP gas to heat and remove some stubborn bolts.. If you are not use to working with a flame then let some one who is familiar with it do it.. You don't want to burn up your vehicle. As far as removing the manifold bolts off the head that will be easy. The difficulty I had with installing my headers was that the mounting bolt holes were not drilled on the header properly and did not line up. I just re drilled some of the ones that was off by one drill size and the headers bolted up with no problem. If you find that you have that problem re drill the header bolt holes but don't try to force the bolt through the bolt hole if there is resistance you will cross thread the the bolt hole in the head. Don't worry you can do this job. Take your time. Are you handy with tools? Do you have good quality tools like Snap On. Are you use to working on you back or are you lucky to have a lift and use safety goggles..
