QUALITY STRENGTH PERFORMANCE SINCE 1981<br />
The PRO1 24° 365cc CNC is for uncompromising<br />
performance and racing applications which favor<br />
high RPM power over low end flexibility. Best for<br />
big cubic inch, high RPM use.<br />
Every intake port, exhaust runner, valve bowl,<br />
and every combustion chamber is 100% CNC<br />
machined on special dedicated PRO1 castings.<br />
Our 5-axis, computer controlled machining centers<br />
produce compound curves and complex<br />
shapes that no human could duplicate with a<br />
hand grinder.<br />
Assemblies include Stainless Steel valves,<br />
premium springs, locks, retainers, guide plates<br />
and seals.<br />
Heads are sold individually.<br />
