Desirable set of vintage Harley-Davidson Ironhead Sportster 900 dual carb cylinder heads, purpose-built for early performance and drag racing applications. These heads represent a classic period modification from the 1960s–1970s when racers pushed the limits of the 900cc platform by converting to dual-carb setups for increased airflow and horsepower.

Unlike standard single-carb heads, this set has been modified for dual intake configuration, making them ideal for a vintage drag bike, hot street build, or period-correct chopper. These are getting extremely difficult to find, especially in unmolested, usable condition.

PART DETAILS:
OEM Harley-Davidson Ironhead Sportster heads
900cc configuration
Dual carb / dual intake modified setup
Cast iron construction
Early performance / drag race conversion

CONDITION:
Used vintage condition. Heads are solid overall with no visible fin cracks or major damage. I do see one crack on intake port see photos. Show normal wear, carbon, and patina from age and use. Fins are largely intact with only minor imperfections typical of vintage pieces. Dual intake modification appears cleanly executed. Will require standard cleaning, inspection, and likely valve service before use—as expected for performance vintage heads.

I do my best to describe everything accurately, but I don’t know every single detail for every year and model. Please double-check the part numbers, look closely at the photos, and verify the dimensions to make sure this is exactly what you need for your specific application. 

If you need a second look, additional info, more measurements, or extra pictures, just shoot me a message—I’m happy to help you get the right part the first time.
