I'm pretty sure the 2UZ-FE's have hydraulic lifters, so no adjustment is needed.
What you are probably hearing are the injectors or simply valve train noise. I could faintly hear mine, but when I upgraded the braided ground wire from the chassis/cowl to the engine block, I noticed the noice was much more pronounced. I put a more solid 0/1 gauge wire in place of the small braided wire and I'm sure it transmits much more of the valve train noise to the cowl, and consequently, my ears.
I've had several motors with solid lifters in the past and the noise your hearing does sound a lot like solid lifter noise!
