I have the heads and barrels off and see Buell cast on the head and some obvious smoothing around the valve guides but not sure if it was done after the fact. it also has Andrews N6 cams. any tips are much appreciated.
I believe those bikes were stock with N6 spec cams. The heads should be lightning heads which have a 62cc chamber and aren't considered good performance heads. I haven't heard about any factory porting on them.

For more head information and photos go to Hammer Performance.

You don't say what kind of drag racing?
