You can install the manifolds easier if you slip the bolts into the manifold bosses before you place the manifold in position. That way, you won't have all that bolt length getting in the way. Another tip on installing heads alone is to get a couple of old head bolts or some all thread to use as dowel pin guides. Cut the heads off the old bolts and slot the end for a screwdriver. Then, when you are leaning over a fender holding that monster, you can slide it down the dowel pins and it'll go right in place without slipping and ruining your new head gasket. You only need 2 pins for each side to be effective.
