Scorpions are actually some of the quieter rockers out there. Noise is more likely from the cam setting the valve down hard or throwing the rockers around brutally.

Another reason I go with custom cams, the custom grinders for the most part are really big on picking up and setting the valve down gently with the cam profile, and being gentle with the valvetrain; so the valvetrain lasts longer and makes way less noise.
