Seat of the pants feel, i find is the best way for me to tune suspension. The main purpose of the blocks is to control coupling between the front and rear torque arms. When i apply my body weight to my sled, i watch, and the rear torque arm will also touch the blocks and i have a race sled with really stiff springs. I am asuming that your blocks are already rotated to the lowest setting. Another possibility is that the front limiter strap has been pulled tighter, check yours out, might to need to lengthen it. Otherwise, i wouldn't worry about it. Good luck!
