just realized... i never reset the ecu after changing the o2 sensor.. so thats what i'm doing now **crosses fingers**
correct way is warm up car, shut if off, pull ecu and backup fuses from under hood fuse box for 15 min, replace and let car idle for 10-15 min without touching the gas right?

correct.
If you haven't installed the gasket kit, maybe check the mechanical timing but I really doubt it's the issue. I also doubt it's in the valve adjustment. To cause that hesitation, I can't see the adjustment falling out of spec that much. But adjusting them would be a good idea with valve cover coming off.
Those GSR heads are cumbersome to get tools into. You probably know they make a tool for adjusting valves but you can also weld an old wrench and a deep socket 10mm together. It works well. Also....feeler gauges that have the 30 degree bend in them makes things easier. Not sure how your hip is doing. I know my back is angry after I sit over a car for that long.
Have you checked volts on the TPS yet? They seem to fail like crazy with K-series but it seems B-series hold up better.

I agree.
Volt meter option is a pretty easy one to work with. Ground one and poke the other through the correct wire. It's kinda hard to poke through the insulating cover though. Might be easier to make contact on the ECU plug. I used a sewing needle near the sensor and it was a bitch.

Injector cleaner and replace TPS. With the miles it's ready for full tune up like you did and replacement of suspect sensors. Many times it's cumulative and not any one thing specific. @160K miles, the injectors could be well past injector cleaner. They can both dribble at idle and not flow enough at speed or you could have some combination with some cylinders rich and others lean.
Let us not forget the timing belt and water pump. Yeah, yeah, yeah, I've driven several 160k+ wrecks around so, done this drill before.....
EDIT: PUT SOME ANTI-SIEZE ON THE SPARK PLUGS.
