difference between d16z6 and d16y8 pistons

what is the difference between a d16z6 and a d16y8 piston? they have a different part number for forged ones.

I have some 9.1 to 1 compression d16y8 srp pistons, what will the compression be If I put them in my d16z6?

healtoe site says the compression height is about the same, the total height dosn't matter because the forged are shorter than stock pistons, I compared my old cp pistons for a z6 with the y8 srp pistons and from the wrist pin up it looks like the same height.
so it should be real close to 9to 1?
