Found some more info on that sleeve
Reader's Digest version:
Passenger side: Throw out the cardboard gasket. Reuse your factory one or get a new OEM one from Ford. Spray the bolts with PB Blaster before you start. It will help loosen it up.
Drivers side: The exhaust manifold bolts have a shoulder. On some cars, it prevents you from tightening the nuts far enough to make a seal. Some people get replacement bolts from NAPA. Mac started including those metal sleeves so you don't have to get new bolts. Just slip the sleeve in the Prochamber leg that meets up with the exhaust manifold. It acts like a filler/spacer.
