Would this be for the Preditor 420 cc engine by any chance?

Haha no it’s the 212, I need more money for that I’m only 15 lol
22lb valve springs is going to require a new billet rod as well. With the 22's, there is going to be no valve float, so the RPM's will go through the roof. Stock rods are not made for that kind of abuse

The cam calls for stock springs.
10.8 lbs.
Why do you want to run 22 lbs springs. Are you floating the valves?
It may cost you some power and some premature wearing of parts.
Generally I would want to run the lightest springs that prevent float at my engines max RPM.
Camshaft lobe design plays a huge role. The stock springs might cause valve float at 5500 RPM with the stock cam. The stock springs won't cause valve float until a higher RPM with the CL2 cam because the lobes are shaped differently on the camshaft.
If you are floating the stock valves (somewhere around 6500 RPM with the CL2, then I'd say go ahead and do it, but like Landuse said - we recommend billet connecting rods when turning higher RPMs than stock springs allow.
Target (MAX) RPM: 6200-6700
Spring Pressure (In / Ex): 10.8 lbs
Valve Lash (IN/EX): .003"
Ignition Timining: 31-32 Deg BTDC
Newly designed intake and exhaust lobes allow the CL-2 to run at higher RPMs before the engine goes into uncontrolled valve float. This is a great cam for any stock Chinese OHV class."
