I am wanting to buy some heads from a factory Dyna 103. Through my research I have been able to find that the factory touring bikes have head part numbers 17728-08, and 17729-08. What is the part numbers for the dyna 103 heads with acr?

 

Take a look at Ronnies Parts Finder, 2012 FXDWG 103, 17729-08 rear and 16500023 front. Is that what you were looking for?

 

You are awesome I am going to save that site

 

can get cnc ported factory heads for a couple hundred more than the factory 103 acr heads...although they will have the extra mount holes by the front exhaust flange because they are made for 09 and up baggers also. i had them on my fxdb and they seem to work out well

or find a used set of ACR heads on ebay, it would be crazy to pay retail for stock heads...if you go the used route remember bagger heads will fit your dyna
i sold my stock 96 heads(i had them tapped for MCRs) for $275 on ebay, so you will be able to get back some of your investment


remember ronnieharleydavidson to look up part numbers, i preach this to people it is much easier than having to ask, and you really do learn tons of stuff about bikes when checking out those diagrams
