Billet
Head,
Cover & O-Rings
A
must have for the Polaris racers and performance riders.
Our
billet, 2 piece head, is a complete design, and not just a machined
copy of the original stocker. It provides concentric water flow,
thus preventing hot spots. Sealed to the cylinder with O-rings
to create a metal to metal contact, providing even engine temperatures.
The improved combustion chamber pocket and squish area, increases
horsepower and torque. Additionally, the head allows girdling
through the cylinder to the crankcase, providing a much stronger
and durable package.
Girdle
kit is optional. Not for use on 416 PowerMAXX.
