2005 lx sport.

Car will overheat while on park or even when driving on highway with ac on. 180 degrees thermostat and tuned by marty. Once the ac is off, temp will drop down to 190-195f. Now this is in 90 degrees weather and higher. With ac on, temp will rise to 220 and thats when i will shut ac off. Ive hosed down the radiator fins and condensor twice. Removed thermostat and tested in boiling water and its good. Fan is working as it should. Ac on, fan speed goes up. What am i looking for here?
I should also say that this started happening after my small engine build. I added edelbrock intake manifold, comp cam stage 2 with valve springs and rebuilt heads from modularheadspeedshop. 10.5"converter and some other small goodies. I do have a stewart water pump which was working great on my stock motor. Stainless works long tubes with 2.5" exhaust.

So why after this build im getting overheating issues with ac on.
