05+ is all the same except pistons on L32 are forged and L26 are not and the difference in compression.

L26 = 9.4:1 Compression
L32 = 8.5:1 Compression

L26 rods are smaller than L32 rods...so sit a set next to each other. Oil pan is different...L26 heads and L32 heads flow better and have slightly larger valves as well.
