They do not have the front engine boss like the 09 and later baggers but could be added by a machine shop. They do have the beehive springs however. They have not been installed since the port work was completed. I was going to use them on a bike that I just sold but will no longer need them due to the bike selling. I will probably be trying to do this build again in the future on another bike at some point but I just got an offer on the bike that I could not turn down so this set of heads are now for sale. They can save you some down time for your build and you'll have an extra set of heads when you pull yours apart for your build. Pictures available upon request. $750 OBO shipped CONUS.
