First it might help if you listed what bike you have, year and model.

The Buell XB heads, which are standard on 04up 1200 Sporties, are considered an improvement over the Thunderstorms.

Just reworking or replacing the heads won't do anything for you. What are you trying to accomplish? At 23k, I'd probably do pistons and cams and then address the head issue. NHRS does a lot of Sportster motor work. The owner, Dan, will also give as much free advice you want. Give him a call.

Yeah dan know his stuff and is really helpful. If you have the means i would suggest the 1200R heads. With cams and an ignition module you wont beleve the difference in power. 117hp. its rediculous
