Custom rods can be used to increase compression but very little ( deck height limitations) but you also need to consider rod /stroke ratio. The 2.0 has a very good rod length to stroke ratio 1.92 to 1 ( if memory serves me) and any substantial increase in that ratio is detrimental (counter productive).
Increased rod length on all other Porsche 911 based engine is beneficial. When Porsche increased the size of all 911 engines after the 2.2 liter they shortened the rods to try and maintain a specific engine dimension. This rod shortening causes a plethora of problems not the least of which is piston side loading.
