SLP has done it again! 

Providing more horsepower through combustion chamber design, these billet heads for the Patriot 850 engine deliver an impressive 6 horsepower peak with an additional 5 to 7 midrange.

They are designed to maintain compatibility with 91 octane pump fuel for optimal reliability and consistency. 

These heads are approved for use with stock engine/pipe configuration as well as an SLP lightweight silencer and an SLP intake kit (Stage 1.5) with no fuel management changes required. Other combinations may require additional fuel management and/or higher octane, please inquire.
