I have a 4.5 inch short arm suspension, with shackles and blocks in the back, the back sits slightly higher than the front.... Is there a way i can lift the front another inch or two without pulling back the front tires too much?

 

Spacers

 

i thought about them coil spring spacers.. but wouldn't thats still affect the arms? pulling the tires back?

 

If you still have the stock control arms, then you are already exceeding their limits. Dump the crappy lift blocks and build a bastard leaf pack that will match the front heigth.
