Differences in TSX pistons?

I noticed 3 different part numbers for the years 04-05, 06-08 and 09 TSX. Does anyone know the difference in all 3 pistons and which would be better for a K20/K24 setup since I will be picking up a set asap for the swap.

Damn so what do you think my compression ratio will be with the K20/K24 setup along with the 09 pistons? just using k24 accord crank and 09 tsx piston and tsx rods with a k20z1 head. From what I looked up the k20/k24 frank setup is usally what about 11.6:1 compression so what do you think would happen if I go with the 09 pistons any benfits or would the compression but that much higher then 11.6:1
