Like Todd said you have to stay on top of spring pressures with the puck style lifter. If you dont the cams are so aggresive these days it actually throws the lifter off the lobe, when it comes back down and makes contact the puck gets knocked off. Im extra cautious about spring pressures simply for that reason and probably have WAY to much, but (knock on wood) ive used the same schubecks that Jeff Velde gave me 10 years ago that came out of one of his engines. Same thing applies for the roller lifters, thats the reason they break the wheels off, not enough spring pressure and everything starts bouncing.
