New Headers

Well, I'm going to do it: I plan on buying the SLP exhaust for my GT. However, before I do that, I might also get TOG headers. Buuuuutttt, first I'd like to know if I'm going to have to pull the engine to put them on or not. I know in some vehicles you dont have to, in others you do. I'm assuming I probably would have to with my car, but confirmation would be appreciated.

if you lift the engine on a block it makes it easier to get at the back bolts on the factory headers , theres a couple bolts you have to pull to allow the engine up and slightly forward when it rests on a wooden block as you lower the car on it. Then the front and side ones (there 3 peice) and where they all come together as one exhaust pipe. Does that help?
