Impossible to diagnose from this limited information but a first guess would be one or more lifters going bad. You state that you recently had engine work done....a common problem leading to lifter damage is reuse of a worn lifter tray or use of a poor quality after-market tray. Either allows the lifter to turn in it's bore which damages the lifter & if not caught early, could damage the cam. Get back to your engine builder for a full diagnosis.
