Personally I would take off the bottom manifold flange nuts and then remove the whole manifold and then replace the flange gaskets as well.I think this is the easiest way to do it.Before you put all the nuts and bolts back on give the bolt threads a coat of anti seize grease.Do you mean soaking in WD40 after removal or before,as a good spray before can help to release seized bolts and nuts,and soaking afterwards is also fine and make sure you give the threads a good wire brushing and then the anti seize grease.
