How to tell a 2.3 HO intake mani from a 2.3 LO intake mani?
and How to tell if a 56mm TB is HO or not or if they are all the same?
the 2.3 HO manifold is bigger than the LO.
and i would measure the TB to make sure its 56mm

Im a Xbox 360 fanboy...and damn proud of it!!
All 2.3L TB are 56mm. Mine came from a SOHC Quad.
