Listing #: 497152799
For sale here are a set of Buell XB high performance heads rebuilt to stage 3 (hot street or race application) by Nallin Racing Head Service in Longmont Colorado, USA.
NRHS are at the top of the game in the USA in high perforformance street/race Buell and Sportster porting, headwork and engine components. They hold numerous Bonneville AMA BUB, and AHDRA drag titles. Visit

These heads, parts and custom work cost over $2000nz and that doesnt include shipping or taxes. $1100 is a bargain. If you want to play power games you gotta come to the table with parts like these. With the right cams pistons cylinders and carb you will easily pull 120-130hp 110-115fpt on the dyno.

All you watchers... Im only going as low as $1100. Any lower and Im giving away beautiful heads, wich I wont do. Ill just keep them for another project. If $1100 is too much for you then dont bother watching. Thanks.

Have been dual plugged, with the sensor in the rear head removed and machined with an insert for the second plug, see pics
