VZ GTO. VS LS1.
Is there something damaged on your vs manifold or are you looking at doing this as an upgrade? If the latter, there is no benefit in fitting the later model inlet manifold as they are the exact same item. There is only one minor difference between the two and that is the vs manifold has one extra threaded hole under the thermostat housing for the coolant temperature sender to screw into. This thread does not exist on the vx manifold and would therefore need to be added if you were to use it. The thread is 1/8 NPT from memory and it is a tapered thread. No ecu reprogramming is required.
There is also minor differences with the plenum chamber that I can elaborate on if required.

It's only worth changing if your planning on running heaps of boost, as the latter model plenums (VX-onwards) are slightly different in a sense that they distribute the air better between cylinders. In saying this though the plenum spacers do a better job of this ;)
