Ticking valvetrain noise from fresh engine

Ok, Is there a roller cam in it, or did you go with a flat-tappet? At any point i wouldn't keep throwing new parts at it, If its a roller cam then the lifters will not rotate, Roller cams will make some noise, but there shouldn't be any clatter, they tend to be a bit noisier when you increase the throttle, you can't here the cam when the hood is closed or in the car, shouldn't be able to anyways in most cases, now what i would do at this point is take a video of it with sound of coarse & post it as a link so we can hear it, this will help.
