03 vs 08 heads

[08ultra]

Can I use 03 heads on a 08 bike, and if not what model years are compatible with the 03 heads? Thanks.

You could if you wanted to but why would you want to?

Iwan,
The MOCO changed top motor mount in 08, you could use them if you have the mounting holes put in the 03 heads for 08 top mount and get new intake flanges for 05 or earlier . The heads are interchangeable for year models 99 thru 07 but the intake flanges with have to be changed on 06 and 07 as well (06 and later intake flanges are centered) (05 and earlier are off set mounting screw pattern). The 03 heads have off set pattern, hope this helps
