The upper factory block has the bottom out ear on it that catches the rubber snubber when truck is overloaded. If you can configure it so that the springs max out and the right deflection without exceeding travel amount go for it.
You risk damaging the spring pack if springs get overloaded. They can bend and when they do they don't come back.
The most important thing there is tight u-bolts holding the rear axle to leaf springs. You can pull the upper oem blocks just be mindful that springs do have a maximum deflection.
