1. 4G91 block + 4G91 head
2. 4G91 block + 4G93 head
3. 4G92 block + 4G92 head
3. 4G92 block + 4G91 head
4. 4G92 block + 4G93 head

Given all the engines are Naturally aspirated, I think 4G91 head + 4G93 block will have most torque and power.

4G91 head having the smallest clearance volume among the other heads and 4G93 having the biggest displacement volume, will produce strongest static compression ratio.

Naturally, a bigger displacement will give better torque.

PS : I'm assuming 4G91 being a 1.5 will have smallest clerance volume.

joeker's comment is sort of true but u'll notice power tapering off horribly above 5K RPM
