X, Y, Z assembly Rod lengths

I am eagerly awaiting my Prusa i3 MK2 kit assembly to be delivered. I have read up a lot on the bearings and rods and want to order some prior to delivery to get better noise and performance. Is there an official length of the X, Y, Z axis rods. I am going to order some new bearings and new rods but cannot get confirmed lengths

After research I have in my cart the following items, just need community confirmation on sizes. Are the following lengths correct:

330mm for Y

370mm for X

320mm for Z

Found in assembly instructions :

330mm for Y axis

320mm for X axis

About the length of the Z axis, it's seems to be 370mm.

All linear bearings are LM8UU. I will not choose LMU-8N because they have no seal to protect the balls of the bearing.

But that's exactly the same linear bearing as LM8UU. If you want high performance and are able to find LBCR 8-2LS or LBBR 8-2LS they have more ball rows so they better distribute the efforts on the rods
