1200 Sportster Heads

- increase in compression ratio depending on piston choice
- heads are fully ported, resurfaced, and have had a radius valve job
- contains new valves (1.725” & 1.480”), guides (manganese bronze), springs (titanium top retainers) and seals (Viton)

These heads are best when used with the Wiseco 1200cc domed pistons. This is the only way to get a significant increase in compression.

We highly recommend all 1200 Sportster owners consider using 883 head castings for porting work. It all costs the same but the ported 883 heads will make more horsepower and torque. You will probably find many 883 owners willing to trade and even pay a bit for a trade. You may like to take a look at our 883 heads to see why before you make a decision.
