The 05 and up cases have thinner cylinders. But didnt think there was a differance on 01-04.

Yeah ther is a differenec int the cases 01-02, 03-04, 05-06, and i believe 07 +........

Yeah the crossover hole were added in 03....
THen the holes got bigger in 05 and i think they grew in 07.

The 05-06 have bigger hole and make better power but when u do a 3 mil they get real weak.
