Noise from the valvetrain is normal with almost any aftermarket cam.
Pushrod is measure using the base circle of the cam and preload measurements. Thats kind of hard to tell you since you have zero knowledge about the cam in the car, nor has the base circle ever been measure.
Dyno the car. If there's no dips in the higher RPM's your valvetrain is probably fine. If it makes you feel any better, pull the valve covers off, loosen all the rockers, put #1 at TDC, and re torque them all via GM sequence.
Have fun
