Running hot.. Can't figure out why.. Please help.

Hi guys. So I'm running hot again. Everything was good until I replaced my carb. Here is my setup

318
Aluminum radiator
Distiller water with water wetter
Electric fan
160 thermostat
High performance water pump
Msd coil
1850s 4 barrel Holley carb with secondary vacuums with 65 jets

It's seems as if I'm running too lean. I purchased the larger jets and as thinking of re-jetting it with the 69 size jets.

I also checked my plugs and they are white so definitely running hot

My timing was just adjusted to 10 degrees.

Any suggestions?

Ps I live in Vegas and it's 100+ degrees and I'm running around 210...that's the highest.

Any help is greatly appreciated.
