To the original question of the thread, I copied the '07 FLHTCUSE parts books' pages on the CVO 110 and the parts shown in the kit breakdown for the 110" kit (29866-07A) in the P&A catalog and compared major components--I did not check the crank as this is a seperate purchase item for the 110 kit if doing an 88 or using the stock crank in the 96. The CVO crank is PN 23739-07; don't know if this is the same crank used in the 96.
The cylinders are the same (PN 17285-07); the pistons are the same (PN 22284-07); the cams are the same (PN 25638-07, SE 255); the valves, etc. in the heads are the same; the part numbers for the heads themselves are, however, different: Kit heads are 17251-07 (front), 17252-07 (rear); CVO 17253-07 (front), 17257-07 (rear).
I didn't bother to check other components. Note, the 110" kit suggests replacing the OEM cylinder studs with SE High Tensile Studs (16505-01).
The instructions for the 110" kit come with very specific case boring instructions and specs--personally, I think it unlikely that there is a 110" specific case; MOCO probably does the same thing with the stock case per the specs in the kit instructions and assigns the modified case a part number.
Perhaps someone else can shed light on the heads.
