LQ4 Identification

So I'm waiting for an LQ4 I bought to get in by freight this monday but I'm still not sure on the year. I know that 99-00 had a longer crank compared to the 01+. So far what I know of the engine is that it has dome pistons, 317 aluminum heads, and this pic showing the rear part of the crank (but since I have never seen an LQ4 crank I can't tell the difference between the older and newer versions).
