I bought these heads as back up set. these are known as fuel injection heads as they came out. in 2007

They also be work  on a carburetor bike, just need a wider intake.

The 2004-06 heads are getting harder to come by now days.

I have a 2001 Sportster with these heads. Bought a Intake to fit from HAMMER PERFORMANCE.

These appear to be in bolt on condition.

the Front head has silver high lighted fins, and the rear is not (black)

All threads look good, no broken fins.

They are double Boxed for shipping

Email with any questions

the shipping box is 12x12x12 weighing 22 pounds
