You need to get your compression UP. Your engine is only 9.4:1. Get your compression up around 10.6:1 (which alone will give you a ~5% increase in torque) and add something like a 206/212 XFI lobed cam.

Another thing i think that contributes to my low end torque is the 5.3 heads on my lq4.This bumps up my compression to about 10:1.
