Leveling 2000 Tacoma?

I'm wandering how to lift & 100% level a 2000 Toyota Tacoma V6 ex. Cab. I bought one from a friend it has a rough country leveling kit installed and had the 3" blocks in rear. The truck looked terrible with the rake. I have taken the 3" blocks out & installed 1" blocks, but still has a rake to it. So my question is what do I need to do so that there is no rake, but still be
Lifted? I don't want to have to drop back to factory in rear. I like the height, but front needs to be lifted to match and have no rake. Thanks!

Pic attached was with the 3" blocks. It was worse looking on level ground.

 

A tape measure.

Measure the height difference between the front and the rear. Then buy what size you need, based on your measurements.
