If a lift is not available, raise the vehicle and support on quality Jack Stands on level ground. Do not rely on a jack! We use sealing beads on all our headers. The raised bead creates a better seal virtually eliminating leaks if installed properly. It is important to install all header bolts lightly snug and then tighten to factory torque specs starting in the center and working outward. Before starting, allow the vehicle to cool, disconnect the battery, and spray a penetrating oil on alI hardware and fittings that will need to be removed. Once you remove your manifold, clean the sealing surface on the head of any old gasket debris or carbon build up.
