The difference in the numbers is the size of the intake valves.
The other difference in the heads is the size of the combustion chamber which is sometimes determent by the humps on the front of the head. 2.02 heads usually have 2 humps (double humper) on the heads. But 2.02 valves can be put in other heads by installing bigger valve seats and valves.
If they are 2.02 heads the space between the intake and exhaust valve is about as thick as your thumb nail.
The only 100% way to tell is to remove the heads and measure the intake valves.

The heads on the 2.liter cracked between the valves. The 2.2 valves were a little farther apart to help to prevent this problem.
Check the size of the head of the valves. The 2.2 is a little bigger

Measure the diameter of the intake valves at their widest point (facing the combustion chamber). You'll need a vernier caliper or 1-2 or 2-3 micrometers. If in fact these are the 2.002 or 2.000 heads the valves will tell the true story.

The difference is in the size of your wee wee. If you are a girl, go with the sb2. A real man would get the sb2.2
it will make girls think you have a big wee wee. even though thats not the case.
