What are the valve sizes of the g180z and g200z heads?

As far as I know, if the engines are from the same year/model, then they have the same head.

So you obviously cant compare pollution 1600 heads to pre-pollution 1800 heads, as an example.

don't know the size but if you want bigger valves then get a early model 1600 head tx or tc they have bigger valves than the later models.

the g180 inlets are 42 mm, g200 either 39 or 40 mm. The exhaust valves Im not sure, I think they are all about the same size on all the heads

So a g180 head has the same size valves as a tx g161 head?
