Pretty sure that LQ9 always had the LS2 style rods with full floating pistons and coated skirts. Midyear '04 LQ4s got the same rods and full floating pistons and coatings. From MY04 up the only diff between the two is flat top pistons vs dished.

And any LQ4 in an '05 or newer will be the newer setup. Vans, trucks, SUVs, h2, doesn't matter.
