I don't have any here at work, but I might at home. You should install the upper manifold log heat shields with 3 bolts each before installing the engine, but I'm guessing you're having trouble with the lower heat shields that are for motor mount protection. Those can't be installed until the engine is on the frame horns. The bolts go through the saddle brackets with the stud pointed upward. After the saddles/mounts are secure, then you can install the "L"-shaped heat shields over the stud. The long leg of the heat shield goes down and to the rear between the rubber mount and the exhaust manifold. If the first one doesn't want to go on, try the other one - it's easy to get them mixed up.
