Z20E connecting rods

[Dirttrack510]

I am trying to build a long rod 2.1 liter frankenstein engine. what is the difference between the Z20E rods and the L20B rods? The company I was going to order the rods from shows the same part number for both rods. I was under the impression that the Z20E rod was a little longer than the L20B rod. Any help would be greatly appreciated.
