Some tips/tricks you guys didn't happen to mention. If you unbolt the downpipe before ratcheting the engine forward it will have less load on it and the bolts may come out easiers.
Loosening the rear subframe bolts and allowing it to come down about three inches gives you an easy way to remove and put in yoru rear manifold/header.
The two fasteners on the ends of each head that hold the header/manifold are studs. Removing the studs (5.5 mm) helps gain a lot of room for taking the manifolds out and putting the headers in.
