I'm not positive on the size (its a Torx bit of some sort) but your idea isnt gonna work anyways, you will have to take it all apart because the runners are in the way of some of the manifold base bolts.

The top runner-to-plenum bolts are for sure Torx T-40.........think the lower ones that go from runner-to-intake are the same, but not 100% sure.
